Fourteen generous members of the public were beneficiaries themselves on 22 September, when they were invited onboard HMAS Choules for a day.
Choules hosted the group who had bid at charity auctions to experience a day at sea with the Royal Australian Navy.
The experience included a tour of the ship as she sailed in and around Sydney Harbour and the opportunity to witness some of the day-to-day work of her crew.
Highlights included seeing Choules operate in company with HMAS Arunta, watching the professionalism required on the bridge of a Navy ship, and experiencing her impressive amphibious capabilities on a boat transfer back to Sydney by a Landing Craft Vehicle Personnel (LCVP).
Mr Ian Bollen, who came onboard with his two sons, Zac and Josh, said that what they saw was a once-in-a-lifetime opportunity.
"What we saw was way outside what I consider day to day life-it was an insight into the complexities of the Navy," he said.
Significant amounts of money were bid for the experiences, with funds raised going to charities including the Sydney Children's Hospital, Odyssey House, NSW Cancer Council, Royal Flying Doctors Service, Legacy and the Sydney Heritage Fleet.
