Sprinter Cate Campbell and reigning Olympic champion Kyle Chalmers will spearhead a 70-strong Australian swimming team named for next month's Commonwealth Games in the Gold Coast. 

Campbell, a five-time Olympic medallist, returned from a year's sabbatical to win three gold medals at the Australian trials to secure her place in the team.

She clocked a time of 23.79sec in the 50 metres freestyle, 0.05 seconds inside her own national record, while also triumphing in the 100m freestyle and 50m butterfly.

Chalmers, the reigning Olympic 100m freestyle champion, is also chosen after a 200m personal best of 1min 46.49sec at the trials.

Teenager Ariarne Titmus represents the next generation of talent when she became the first Australian women to win the distance freestyle treble at the trials in 14 years.

The 17-year-old triumphed in the 200m, 400m and 800m events to equal a feat last achieved by Linda McKenzie in 2004.

The squad for the Games, due to take place between April 4 and 15, includes 21 Para-sport athletes.

Three sets of siblings are chosen, with Cate Campbell joined by sister Bronte, as well as Emma and David McKeon and Kaylee and Taylor McKeown.

Kaylee McKeown beat reigning world champion Emily Seebohm to win the 200m backstroke at the trials, although both are chosen.

James Magnussen, the 100m freestyle world champion in 2011 and 2013, earned a 50m berth as he also returned from a year off.

"I think we've got, almost without exception I'd say, the best people in their best events," said Australia's head coach Jacco Verhaeren.

"I think that's important because if you want to defend titles and want to make the most out of the medal prospects in five weeks' time you need your best people there.

"We want a full team and we want to compete in every event for medals - it's that simple as that."

Australia were comfortably the most successful swimming nation at Glasgow 2014 with a total of 57 medals, including 19 gold.
