On 29 January 1951, Sydney was part of an eighteen-ship fleet present in Sydney Harbour to celebrate the 50th anniversary of Australia’s Federation. Following this, the carrier joined a multinational training exercise in south-east Australian waters, then visited Hobart for the Royal Hobart Regatta. During the exercise, a Sea Fury accidentally fired four practice rockets into the superstructure of the New Zealand flagship, HMNZS Bellona: although an inquiry concluded that the pilot had unintentionally pressed the fire button, it was later found that certain signal frequencies transmitted by Sydney‘s radio aerials could trigger a Fury’s firing circuits.
