Joe Salisbury got the better of fellow Briton Dan Evans as he progressed to the second round of the Australian Open men's doubles alongside Rajeev Ram.
Salisbury and American Ram, the 11th seeds, beat Evans and Australian John-Patrick Smith 6-1 7-6 (7-3).
Britain's Luke Bambridge and Japanese partner Ben McLachlan lost 7-6 (7-4) 7-5 to Bruno Soares and Mate Pavic.
Jamie Murray and Neal Skupski's opening match was postponed until Friday due to courts needing to be cleaned.
Play was delayed on the outside courts because they had to be power-washed after dust and mud fell with the rain in a storm in Melbourne on Wednesday.
