Petty Officer Geordie Bunting
There was a sharp hiss and then an almighty explosion.
Crew Member / Submariner
Bang.
Commodore Peter Scott
We heard flood, flood, flood, flood in the lower motor.
Cameron Stewart
The flood. The closest Australia has ever come in peacetime to losing a submarine and its entire crew.
Commodore Peter Scott
So we are at deep diving depth.
Petty Officer Geordie Bunting
It was fearfully cold and there was a lot of water coming in.
Crew Member / Submariner
20 seconds, that's all we had.
Petty Officer Geordie Bunting
Yeah.
Commodore Peter Scott
I knew we were in trouble. You have a flood like that and you just go to endless unknowns.
Petty Officer Geordie Bunting
I can remember screaming out at the top of my voice.
Commodore Peter Scott
A ton of sea water is the same as 100 crates of your favourite lager coming into your submarine every second through a hole about that big.
Petty Officer Geordie Bunting
Yeah, it was like being stuck in a washing machine. It was just round and round and round.
Commodore Peter Scott
I didn't want to be the guy who took that crew to the bottom.
Cameron Stewart
I'm cameron stewart and this is the flood. Episode one. Explosion. One of the most remarkable but least known stories in recent Australian history is the near loss of 60 Australian submariners when seawater flooded their submarine HMAS Desheno deep under the Indian Ocean in 2003. For 60 men and women, they had 20 seconds left before they would have sunk to the ocean floor. The submarine would never have made it intact. It would have been crushed like an empty Coke can by the ocean's pressure as it went down. It's a story the Navy glossed over at the time, fearing further damage to the already tarnished reputation of its new Collins class fleet. But for those who were aboard the submarine that day, their lives were never the same again. It haunted the Navy. It haunted everyone who heard about changed the way the Navy operated its submarine fleet. Its impact can still be felt across families and across generations. For the first time, we reveal the full story of the incident they call the Flood. The closest Australia has ever come in peacetime to losing a submarine and its entire crew.
Commodore Peter Scott
G', day, Cameron. I'm Commodore Peter Scott. I retired from full time service in the Royal Australian Navy half a dozen years ago after a career of 34 years, vast majority of which was either in or around submarines in one way or another. Absolute highlight of that career was my command of first H Mayers Collins and then HMS to Shano.
Investigative Reporter
On a dark evening in late 2002, I jumped into a Zodiac inflatable boat which had come to pick me up from the beach in Fremantle, Western Australia. I was a 39 year old investigative reporter and I'd written plenty of stories about the problems facing the Navy's new Collins class submarines, but I'd never been on one. We headed out to the ocean where we were supposed to rendezvous with HMAS Deschano, the fourth of the Royal Australian Navy's six new Collins class submarines. As we raced out to sea, my eyes scanned the dark horizon, seeing nothing. Then suddenly, a huge dark outline of a submarine appeared out of nowhere. We pulled up alongside and before I knew it, I was whisked into the submarine and down the hatch. The commanding officer of the Dechano, Peter Scott, was there waiting for me. He wore a strange grin on his face. I was the last person that he and his crew of 60 men and women wanted to see. A journalist, the bane of their profession.
Commodore Peter Scott
I'm Mike Deeks. I was in the Navy for 32 years, from the age of 15 to 47. My years as a submarine force commander was 2001 to 2005 and so if you recall, that was the time of HMAS Lemon Dud subs. A lot of bad press, leaky propellers, noisy engines and combat systems that had to be replaced because they were out of date are just some the missteps on the way to launching the much maligned Collins fleet. So I spent a lot of time making presentations to all and sundry about dispelling the myths of the Collins class submarines because I had a submarine force that was in somewhat of a quandary. They were loving these new submarines and
Cameron Stewart
all that they brought, but we were
Commodore Peter Scott
getting a lot of bad press at the same time.
Cameron Stewart
It was eventually agreed I could spend 48 hours on board the Deshaino while it was conducting war games against Australian naval ships in the Indian Ocean. I'm 194 centimeters or 6 foot 4 inches tall, so I don't love small spaces. And the Collins class boats, although bigger than the old Oberon boats, are still a warren of narrow passageways guaranteed to bring out the inner claustrophobia in anyone. I recall feeling queasy when the submarine first dived beneath the surface. I kept bumping my head on things, but I did my best to join in. I ate with the crew in the mess, I slept under the torpedoes and I watched them as they listened to the whales and the warships in the ocean around them. The crew quickly got over the fact that there was an outsider in their midst they were relaxed, friendly and surprisingly eccentric. Commander Scott was a submarine commander from central casting, a tall, rangy character who was hugely popular with his crew, not least because of his reputation for calmness under pressure.
Commodore Peter Scott
If I tell a scary story about life on submarines, I'm often asked, why would you do that? And my answer comes down to three really simple things purpose and challenge and people. The people are phenomenal. They tend to be the sort of characters who are driven by purpose and look for challenge. You cannot survive in a submarine if you don't know your stuff and if you can't work with other people. But that doesn't mean that you can't be eccentric. It doesn't mean that you can't be quite a different character.
Cameron Stewart
One female submariner was a heavy smoker who chose to work in a sealed non smoking capsule and who harboured the peculiar ambition of one day sinking her fiance in war games. He was a sailor on the ANZAC frigate Warramunga. And even the sonar operator Melanie Ellerton would spend the day imitating the whale noises she heard on her headphones. When I asked her one day what noise sharks made, she looked at me in the eye and chanted the theme music from the movie Jaws.
Crew Member / Submariner
We have a very secretive lot and very tight crew. What I really, really, really loved about the command on the Shano at that time was very much like a you work hard, you play hard, so you put the yards in, you put your hard work in and you're rewarded for it. The morale was amazing on that boat. I'd loved. I'd love to just relive it again.
Cameron Stewart
The crew even had a peculiar habit of watching submarine thrillers while underwater. With Sean Connery in the Hunt for Red October being played seemingly on a loop.
Investigative Reporter
Our strategy depends on your answer.
Cameron Stewart
The entire fleet will know where we are.
Commodore Peter Scott
Captain, Sonar.
Petty Officer Geordie Bunting
We've just been overflown by a low
Commodore Peter Scott
altitude multi engine turboprop.
Cameron Stewart
I had no idea that just a few months later, these men and women would be fighting for their lives in the very same submarine as it flooded deep under the Indian Ocean. But even while I was on board, there was a major incident. The Duchenne was gliding silently beneath the ocean surface towards its planned skirmish with three Australian Navy ships about 80 nautical miles off the West Australian coast, when I suddenly heard footsteps and yelling in the narrow corridors. Get down the back. Let's go. Yelled a petty officer they called Mango. He took one look at myself and my photographer and bellowed, look after the civilians. Let's go. We're not effing around here. There was an unnerving urgency in his voice as he hustled us towards the back of the boat. An alarm sounded throughout the submarine. Crew members who had been sleeping seconds earlier jumped out of their bunks and ran to their emergency stations. Some were donning fireproof clothing and oxygen masks and tanks. No one was joking. Clearly, this was not drill. We were shuffled through watertight doors that seal the front half of the submarine from the rear. The doors are designed to prevent a fire or flood from engulfing the entire boat, ensuring that at least some of the crew can initially survive a disaster. Commander Scott announced over the speakers that there had been a hydraulic burst in the weapons storage compartment. Two crew members dressed in full fire fighting kit, charged into the compartment where torpedoes and harpoon missiles were suspended. They discovered oil spraying out at high pressure from a broken connection in the piping. I was standing with a group of crew in the sealed back half of the submarine, listening to the emergency siren.
Commodore Peter Scott
The failure of a system like that can be really serious, but there's a lot of risk associated with how it fails as well. So if you have a hydraulic burst, what you have is hydraulic oil being sprayed at extremely high pressure into the atmosphere and it just becomes explosive. So the risk of explosion and fire, neither of which are healthy, on board an enclosed submarine can be really high.
Cameron Stewart
Minutes later, a voice came over the pa. It said, there is no risk of fire. The system is safe, no casualties throughout the submarine. The petty officer, Mango, later apologised for his language, but he said a fire in the weapons room was one of the most dangerous things that could occur. That's what happened on the Kursk, he told me. The crew of the Kursk are now
Commodore Peter Scott
entombed as the Navy races to attempt a rescue.
Cameron Stewart
Every submariner at that time was haunted by the story of the Kursk, the Russian submarine that sank to the bottom of the Barents Sea with 118 crew in August 2000 after a torpedo stowed on board exploded.
Crew Member / Submariner
Western military analysts had been suggesting earlier on in the day that if no breakthrough came within 48 hours that the crew would be in a very grave situation indeed. There's still no firm indication those crew
Cameron Stewart
who survived the initial explosion wrote notes to loved ones for days as their submarines sat in the seabed awaiting a rescue that never came. When I went to see Commander Scott in his cabin after the hydraulic burst, my eyes darted to a book on his shelf. A Time to Die the Curse Disaster.
Commodore Peter Scott
We were in Hawaii at the time, during a maintenance period. Importantly, we also had a lot of our family over in Hawaii, you know, just taking some leave with the crew. So my wife and daughter were with me as the news was breaking each other each day. It was hard to watch that unfold. It was pretty brutal on the families because they can just place themselves in a very similar situation. There's absolutely. This might be the wrong term these days, but there's absolutely a brotherhood amongst submariners. There's not a lot of people in the world who understand what it is to take a naval submarine to sea. So you definitely feel a sense of kinship, politics aside with another navy's submarine force that suffers a disaster like that.
Cameron Stewart
On that day in late 2002, as we glided under the Indian Ocean, I recall sitting with Commander Scott in his cabin talking about the Kursk and about the risks which submariners face. He had his own stories to tell. At just 37 years old, he once helped steer home a crippled British Navy submarine in the North Sea when it was swamped by a wave with its hatch still open, causing seawater to surge in short circuiting computers and sonar equipment. I had no idea that just a few months later, when I was safely back on dry land, the Commander Scott and this same crew of lovable eccentrics would go perilously close to suffering the same fate as the crew of the Kursk.

Commodore Peter Scott
So we were preparing for a deployment which would probably be three to four months long, up into Southeast Asia to conduct a series of top secret missions. And we were pretty well through most of that work up.
Investigative Reporter
Commander Scott chose to test the submarine's systems at deep diving depth, the deepest depth which the submarine is designed to operate at. The actual deep diving depth itself is classified because to reveal it would give an enemy an advantage in any conflict.
Commodore Peter Scott
It's the deepest depth at which you would be authorised to operate in any sort of normal circumstances. Even in a wartime scenario, you think really, really carefully about pushing the boat deeper than deep diving depth.
Investigative Reporter
I'm climbing down the main hatch of the HMAS Onslow, one of the old Oberon class submarines. They are the predecessor to the Commons class submarines. This submarine was decommissioned in 1999, just two years before the Descheina was commissioned. It is a rabbit warren of pipes, wires, equipment of all types, crammed into narrow passageways where sailors and submariners have to walk through for weeks and months on end, gliding silently under the ocean on top secret missions. As the submarine glided ever deeper, the crew responsible for the submarine's technical systems were at their stations, vigilant and silent to watching the depth gauge, their eyes scanning every instrument and piece of equipment, knowing that the water pressure outside was rising with every metre of depth.
Petty Officer Geordie Bunting
Lower motor room is a space right down the bottom at the rear of the or aft in the submarine that houses a fair amount of seawater cooling apparatus, pumps and pipework.
Investigative Reporter
I'm going down to the lower motor room, a tiny room crammed with equipment. This is where Petty officer Geordie Bunting was stationed to keep a watch on flexible hoses. On the day of the flood, there
Petty Officer Geordie Bunting
was myself and two other guys who were in the engineering space in the engine room and for some reason we played paper, rock, scissors as to who was going down the hole and somehow I come up worse off than the other two. So we were just looking for leaks and just hoping that everything held together as it should to put the boat through its paces.
Investigative Reporter
The lower motor room, a crammed space measuring no more than two or three metres, sat underneath the submarine's main motor room. The crew entered and left this small room via a hatch on the deck. Petty officer Jordy Bunting, universally known as Rocker, stood in that small compartment at the back of the submarine, his gaze fixed on a newly replaced hose which is part of the auxiliary seawater system that provides cooling waters for the motors and which is exposed to sea pressure at all times. Then in an instant, his world changed.
Petty Officer Geordie Bunting
There was a sharp hiss and then an almighty explosion.
Crew Member / Submariner
Bang.
Petty Officer Geordie Bunting
And the next thing I remember was, shit, it's getting pretty cold. It was fearfully cold and there was a lot of water coming in. I can remember screaming out at the top of my voice, not that I thought it was heard, that we were flooding. And then, yeah, it was like being stuck in a washing machine. It was just round and round and round.
Investigative Reporter
Luckily for Bunting, Able Seaman Greg Sullivan was standing not far away in another compartment.
Commodore Peter Scott
On the day of the flood, my
Cameron Stewart
role was to be in the engine room bilge and checked the area for leaks.
Commodore Peter Scott
I heard a loud noise and then continued noise that wasn't normal.
Cameron Stewart
It's normally pretty quiet, so I could
Commodore Peter Scott
Tell straight away it wasn't good. Started heading back there and ran into
Cameron Stewart
another sailor who was sounding the alarm. When he finished I said, where's Rocker? Near the front of the submarine. Commander Scott was standing just outside the control room under the main hatch with the two of his most senior engineers, Johnny Ryan and Mango, to see if a repair job on a recent small leak in the hatch had been fixed.
Commodore Peter Scott
For a couple of months we'd had a slight weep or a leak on the main access hatch and we'd been back alongside, worked on that hatch, gone back out to sea to try to prove it and it would still leak. So anyway, the Chief Tiff Johnny Ryan was pretty darn confident that he had it cracked this time. So as we arrived at deep diving depth, the chief Tiff, myself and the chief electrical sailor were all underneath that main access hatch just to check that it was actually bone dry and it was, it was fantastic. So we were happy about that, but not for long. And we were very happy about that until the moment we heard a main broadcast pipe which said flood, flood, flood, flood in the lower motor room. So we are at deep diving depth, the submarine is under as much pressure as you would design the submarine to operate at and we've got a major flood somewhere back aft in the submarine.
Investigative Reporter
The words flood, flood, flood on the intercom were enough to freeze the blood of the entire crew. At deep diving depth, a major flood was the most dangerous mishap the submarine could suffer.
Commodore Peter Scott
John Ryan joined the Navy in 1984 as an apprentice out at HMO's Naremba at Quakers Hill on Deshaino. I was the chief Tiff or the head of the engineering team.
Cameron Stewart
John Ryan was halfway up a ladder checking the main hatch for leaks with Commander Scott when he heard the flood warning come over the speakers.
Commodore Peter Scott
You could hear the words flood, flood, flood but in the background it was like a roar.
Cameron Stewart
Was anything going through your head at that point?
Commodore Peter Scott
A lot of things I think, but nothing in particular. Just shit, shit, shit.
Cameron Stewart
John Ryan sprinted as fast as he could from the front of the submarine to the back to see what had happened. The crew would later dub him Johnny Crazy because he ran towards a major flood and not away from it.
Crew Member / Submariner
So I remember sitting in the junior sailors mess when the flooding alarm came through the speakers. I saw old Chief Tiff Johnny Ryan running back aft and I said, well that's not normal. You know, normally when we're exercising or things happening, it's more of a disciplined exit towards the incident. But seeing that and then hearing the flooding alarm going off and then very closely watching the depth gauge. Yeah, just scary.
Commodore Peter Scott
It was several kilometres deep, so pretty deep preservation. Probably three kilometres beneath us, certainly too deep for the submarine to survive. So if we had gone down in that depth of water, the submarine would would have been crushed before we hit the bottom.
Cameron Stewart
Commander Scott had no way of knowing at that moment how much water Dechano had taken on and whether or not he could get his crippled submarine back to the surface.
Commodore Peter Scott
When you have a flood like this, you go from knowing the state of your submarine in intimate detail, like you can know or pull out the state of every valve, every switch, the contents of every tank, every single detail about the submarine is known. You have a flood like that and you just go to endless unknowns.

Petty Officer Geordie Bunting
Something flew past and clipped my head and hit something and flew back. But it was all split second stuff that went on.
Cameron Stewart
Was your head under the water at any point?
Petty Officer Geordie Bunting
No, it was under the water most of the time. It was sort of up. It was. Yeah, it was cold. It was vicious.
