Triple Olympian Leisel Jones is poised to become the first Australian swimmer to go to four Olympic Games ahead of Saturday's finals action at the 2012 Australian Swimming Championships in Adelaide.

Jones will have to contend with former training partner Sarah Katsoulis and Gold Coast sprinter Leiston Pickett in tonight’s final of the 100m breaststroke, with a total of eight individual swims in London up for grabs.

In other action tonight, Olympic gold medallist Stephanie Rice and world championship silver medallist Alicia Coutts will battle it out for a place in the final of the 200m IM, and that all important top seed.

Defending champion Coutts (2:15.94) went through the semi-finals as the fastest qualifier having already secured a place in London taking out the 100m butterfly final last night, while Rice (2:18.21) will also be looking to pick up another individual swim at the Games.

Looking to spoil their chances after recording the second fastest times in the heats are 16-year-old Taylor McKeown (2:16.43) and Commonwealth Games 200m IM silver medallist Emily Seebohm (2:16.50).

Current Australian record holder Nick D’Arcy has progressed through the heats of the men’s 200m butterfly to be ranked the fastest qualifier for tonight’s semi-finals. 

D'Arcy appeared to have plenty in reserve after clocking a comfortable 1:59.34. He touched ahead of Victoria’s John Goo (1:59.78) and Christopher Wright (2:00.03), who finished runner-up to D'Arcy in this event at the 2010 national titles.

“My time was pretty good, so I think I’ve put myself in a good position,” D’Arcy said.

"I felt really relaxed this morning. I still need to work on my front 100m but overall I’m happy and looking forward to putting in a strong performance tonight."

Three-time winner of this event Travis Nederpelt (2:00.34) qualified for the semi-finals along with Victorian Institute of Sport member Andrew Cameron (2:00.53).

Having already booked places in the Olympic squad over the 400m disciplines, Blair Evans (1:57.86) and Kylie Palmer (1:59.24) will take the fastest heat times through to tonight’s semi-finals of the 200m freestyle. Evans, who claimed second place in Thursday’s 400m IM, and Palmer, who set an Australian record to win last night’s 400m freestyle and holds the Australian record and national title over 200m, will be joined in the semi-finals by 17-year-olds Brittany Elmslie (1:59.41) and Emma McKeon (1:59.54), and Beijing Olympic relay gold medallist Melanie Schlanger (1:59.53).
