The program claimed they had spoken with the only surviving veteran to have served on HMAS Sydney II in an episode named “3D reconstruction reveals more details of HMAS Sydney disaster”, which aired on Monday, May 16.

Interviewee Tom Fisher was described as the last surviving crew member in Perth from the Sydney.

Mr Fisher was quoted as having said "75 years and I'm the only one alive that took part in that”.

But 95-year-old HMAS Sydney II veteran Mr Ravenscroft, who served on the warship between 1939-41 wanted to set the record straight.

Mr Ravenscroft, who reached the rank of Lieutenant Commander, served on HMAS Sydney alongside Mr Fisher.

“I sailed on HMAS Sydney II from the beginning of the war until August 31, 1941 and left the same day as Tom Fisher, the fella who was on the 7.30 Report and three other people,” he said.

“Of those people I know at least three who are still alive. To get up and say he’s the only one still living when he knows bloody well he’s not, I thought was asking for trouble.

“There is myself, Tom Fisher of course, John Brown and Gordon White, who I’m almost certain is still alive.”

The HMAS Sydney is well known for the sinking of the Bartolomeo Colleoni, the Italian cruiser in the Mediterranean in 1940. After which, each sailor on board the ship during that battle received a medal of appreciation, further evidence of Mr Ravenscroft’s claims.

“The people of Sydney gave the ship a big plaque that went on the afterdeck. All of us who were serving on board received a replica,” Mr Ravensroft said.

HMAS Sydney II sank off the Western Australian coast in 1941, it’s final resting place was discovered in 2008.
