Claude Choules is believed to have died at 110 years old in his nursing home in Perth today.
Born in England in 1901, Mr Choules served with Britain's Royal Navy onboard the HMS Impregnable in 1916 at the age of 15.
His son Adrian Choules said of his father:
"He served in two wars but he hated war. He just saw it as a job. He never marched in an Anzac parade he wasn't ordered to."
Mr Choules said " although his father was special to the family, he did not understand all the celebrity attention he was getting from the media. Someone's got to be the last man standing ... he's just an ordinary man" he said
