Glasgow - Australia took their gold medal tally to five from eight swimming events at the Commonwealth Games on Friday after victories for Thomas Fraser-Holmes and Leiston Pickett.
Fraser-Holmes beat off stiff competition from teammate Cameron McEvoy to win the men's 200m freestyle in a time of 1min 45:08sec and will go for a second gold of the night in the men's 400m individual medley later.
There was disappointment, though, for Scotland's Robbie Renwick as the defending champion finished down in fifth behind another Australian David McKeon.
Pickett defended her 50m breaststroke title as Alia Atkinson just missed out on Jamaica's first ever swimming gold at the Commonwealth Games.
Atkinson had set two Commonwealth Games records in qualifying, but despite failing to match those times in the final she still walked away with just Jamaica's fourth ever medal at the event.
And 20-year-old Corrie Scott kept Scotland's momentum going after a fine opening night at the Tollcross International Swimming Centre as she claimed bronze to increase the hosts' swimming medal tally to four.
Australia are expected to strike gold many more times before the night is out as the men's 4x100m freestyle relay team look to defend their title, whilst Alicia Coutts goes for a sixth Commonwealth gold medal in the 100m butterfly.
