ADELAIDE, Australia (AP) -- Sisters Cate and Bronte Campbell will be the first siblings to swim for an Australian Olympic team in 40 years following their 1-2 finish in the 50-meter freestyle final Thursday at the national trials.
Cate Campbell, who had already earned her spot on the team in the 100-meter freestyle, won the 50 in 24.44 seconds. Bronte was second in 24.61 to capture the second individual berth.
Cate, 19, and Bronte, 17, will become the first siblings to swim together for Australia at an Olympics since sisters Karen and Narelle Moras and brothers Neil and Greg Rogers at the 1972 Munich Games.
"We train together and race together, so often we have just had to shut down that side," Cate Campbell said of the competitive streak between the sisters.
The Australian Olympic Committee announced a 44-person team later Thursday for London -- 21 men and 23 women, including 13 teenagers. Half of the team members will be making their Olympic debuts.
Leisel Jones qualified for her fourth Olympics when she finished second in the 100 breaststroke final during the trials. Three-time Olympic gold medalist Libby Trickett will be in London with a relay spot by finishing fifth in the 100-meter freestyle.
Trickett could have gained an individual spot in the 50 freestyle, but finished fourth.
James Magnussen, the world champion in the 100 freestyle, also will compete in the 50 in an attempt for a sprint double, while Stephanie Rice will defend her 200 and 400 individual medley gold medals from Beijing.
"He's the real deal. He's the full package," Australia head coach Leigh Nugent said of Magnussen. "Every time he gets interviewed he has got something you want to listen to and every time he swims he does something you want to see."
The most notable absentee is five-time Olympic champion Ian Thorpe, who announced a comeback last year after nearly six years in retirement but failed to finish among the top six in either the 100 or 200 freestyle in Adelaide, meaning he could not qualify as an individual or relay team member.
Thorpe, however, says he plans to continue his comeback and hasn't ruled out an attempt to compete at next year's world championships or the 2016 Rio de Janeiro Olympics.
Other former Australian Olympians who didn't make the team after failing at the trials were former world record-holder Michael Klim and 2010 Commonwealth Games butterfly gold medalist Geoff Huegill.
