CPO Vandenberg, 46, who had spent the majority of his navy career at HMAS Albatross, died during the Defence Mountain Bike Championship at Mt Stromlo in October 2013.

In a moving ceremony in front of a number of family, friends and work colleagues a plaque commemorating his death was unveiled by his wife Margaret and sons Hayden, Josh and Lachlan at Stromlo.

Earlier CPO Vandenberg’s ashes had been flown to the location onboard a MH-60 Romeo helicopter from 725 Squadron, a project Margaret worked on.

Lieutenant Commander Simon Lam was winched into the site with CPO Vandenberg’s ashes, which were presented to Margaret, followed by a minute’s silence.

Commodore Scott Lockey then scattered his ashes on the course.

Mrs Vandenberg said it was a moving ceremony.

“It was an amazing. Beautiful,” she said.

“I was a bit emotional when the helicopter arrived. Kane would have loved having a ride in the Romeo. He was so proud I had worked on that project.

“Kane is finally at peace. And I feel at peace with it all.”

She thanked everyone for making it a special day.

“I especially want to thank the people who made all this possible,” she said.

“Commodore Chris Smallhorn, Commodore Scott Lockey, 816 and 725 squadrons at HMAS Albatross, Captain Saad, Commander Andrew Dawes, LCDR Rowan, LCDR Andrew Willett, Leut Dave Janszen, CPO Andrew Rolfe, Lindsay Freeman and to LCDR Simon Lam for winching Kane Vandenberg's ashes to us.”
