It’s been around 80 years since the plane it was attached to crashed.
The aircraft and the four men believed to have been onboard have lain here since, undiscovered.
It’s estimated there are between 500 and 600 crash sites across PNG from World War II, but the locations of many of them remain unknown.
After this discovery, there will be one less Australian plane considered missing in action.
The long jungle trek to discover a wreck
The tip-off first came from a pig hunter who stumbled across the wreckage while tracking his prey.
It was up in the hills of East New Britain, outside the town of Rabaul where Willie’s family lives.
But getting to the site to investigate wasn’t easy.
“I collapsed on the way in, so it was pretty tough for me,” Willie says.
He blames himself for not eating enough before beginning the trek.
“And all the river crossings going to the crash site, it was brutal, I ended up going back with a sprained ankle.
“But it was all worth it.”
He went in with a group of family friends. They were hosted by the chief of the nearest village, Barrum, with some of the villagers accompanying the group to the site.
From the village, it takes several hours of trekking to get to the site: through the bush, across several rivers and up and down multiple mountain sides.
For one stretch of the walk, the group used the river as their path, walking through the water for several hundred metres to reach the next point to climb.
They used machetes to cut a rough path through the jungle as they went.
Then they came across the first piece of metal debris.
“I was going nuts, I went bananas. I said, ‘No way, what is this bit of metal doing in the middle of the jungle?’,” Willie recounts.
Pieces of the plane are scattered across the hillside. Some parts look like scrap metal, but others are clearly identifiable: part of a propeller, a bit of a door, several guns.
Willie and his crew had to dig to discover much of the plane which had been buried in decades of mud.
“What helped identify that aircraft was a Beaufort control column,” Willie says.
“It was in the cockpit area, which was underground by about three metres maybe, so we dug down and took out the control column.”
The group could also see bones of the men who had been onboard, parts of a leather watch and the pilot’s vest.
The volunteers piecing together war history
Willie brought the control column and some of the rusted weaponry back to his father David Flinn to try to identify the plane.
David is president of the Rabaul Historical Society and the reason Willie has such an interest in WWII history.
“I used to follow him out to investigate leads that others would provide for him, and we would go and see crash sites,” Willie says of his childhood.
Rabaul was a significant site during the war. Guarded by a small contingent of Australian troops, it was captured by Japanese forces in 1942 and turned into a major naval and air military base.
It then suffered intense allied bombing until the end of the war.
Across Rabaul, huge tunnels still remain that were dug by the Japanese — largely using forced labour — to hide people and materials from the air strikes.
Over on the main island of New Guinea in East Sepik province, the US Embassy recently carried out their own excavations to repatriate the remains of WWII soldiers.
David is among a small group of locals who volunteer to preserve the history and discover crash sites in Rabaul.
He’s glad to see his son take on the interest.
“It’s extremely important because people like us, we’re at the end of our careers. I can’t walk up into the bush like I used to,” he says.
Rod Pearce, another local and an experienced diver, has identified more than 50 crash sites — mostly underwater.
