Defending world champions Mitch Larkin, Emily Seebohm and Bronte Campbell will lead a 31-member Australian team for the FINA World Swimming Championships in Budapest in July.

The team was announced after the national championships in Brisbane late Thursday.

It will be backstroker Seebohm's sixth Australian team appearance and she has won four gold, four silver and two bronze medals from five world championship campaigns.

"I'm really looking forward to Budapest, especially with so many new faces on the team, including 15-year-old Kaylee McKeown and 16-year-old Ariarne Titmus," Seebohm said.

Her boyfriend backstroker Mitch Larkin will be on his fourth world championship team while siblings Emma and David McKeon, James Roberts, Grant Irvine, Brittany Elmslie and Cam McEvoy will all be on their third teams.

World record holder Cate Campbell, who swam the year's fastest 100m freestyle time of 52.78 seconds at the national championships, is skipping the Budapest world titles in the wake of her Rio disappointment when she finished sixth in last year's Olympic final.

"It's still a big part of my life in the future but right now, I just need to find some happy places outside of the pool," Campbell said.

The Australian team comprises 19 members of the Rio Olympic team, including individual gold medallists Mack Horton (400m freestyle) and Kyle Chalmers (100m freestyle) with 16 survivors from the 2015 Worlds team from Kazan.
