The first Australian warship, the destroyer , was launched at Govan in Scotland on Wednesday 9 February 1910. Sister ship was launched at Dumbarton in Scotland on Saturday 9 April 1910. Both ships were commissioned into the Royal Navy on 19 September 1910 and sailed for Australia, arriving at Port Phillip on 10 December 1910. The event was marred by the death of Engineer Lieutenant W. Robertson, RN, who suffered a heart attack outside Port Phillip Heads whilst onboard HMAS "Yarra", and drowned.
