An Australian Navy officer who died on a maritime patrol operation was happiest when he was at sea with his crew, his family says.
In statement issued through the Australian Defence Force the family of Lieutenant Commander Steven Noake describe him as "a much loved husband, father, brother, uncle, son and proud Navy member".
"He devoted 36 years of his life to serving his country and for that we couldn't be more proud of him.
"When not home with his family, he was most happiest when at sea with his crew.
"His life has made a significant impact on all those who knew and loved him."
Lt Cmdr Noake died aboard an Australian Defence Vessel Cape Inscription on Tuesday afternoon.
He was deployed under Operation Resolute which conducts patrols to combat asylum seeker boat arrivals, illegal fishing and piracy in Australian waters and around offshore territories.
Chief of the Defence Force Mark Binskin and Defence Minister Marise Payne on Tuesday expressed their sympathy to the family, friends and shipmates of the deceased.
