You could add in the Breastwork Monitor Cerberus, built at Jarrow and in service with the Australian Navy (when it was still part of the Empire)
It's been fighting to survive since 1926. -

I have always thought about the possibility of raising an old Navy ship, of course you have to desregard and war graves which leave accidental losses (with no loss of life) like HMS Audacious that sank slowly after hitting a mine in 1914, the 1920s gunnery targets like HMS Monarch and the scuttled Battlecruiser HMAS Australia that was deliberately sunk outside Sidney harbour in 1924 as part of the fleet reductions.

No idea about the condition of HMS Monarch or any of the other gunnery targets such as the SMS Baden. I always hope one has survived well in favourable sea conditions.
HMAS Australia -wikipedia - "In 2007, the wreck of Australia was located and photographed. Following the successful use of a remote operated vehicle (ROV) to locate a Black Hawk helicopter which crashed during the Australian response to the 2006 Fijian coup d'état, the New South Wales Heritage Office requested that the ROV be used to verify the location of the battlecruiser and inspect the wreck. The location was correct, and the wreck was found resting upside down and covered in marine growth, 400 metres (1,300 ft) below sea level. The gun turrets could not be found, but the superstructure and masts were present and confirmed the ship's identity"
