Alicia Coutts is likely to get a chance to equal the Australian Olympic record of five medals at a single Olympics in London after she was selected for Wednesday's women's 200m freestyle relay final.
Coutts already has three medals and is expected to also feature in Australia's medley relay team on the closing night on Saturday.
It means she could equal the feat achieved by swimmers Ian Thorpe (2000) and Shane Gould (1972) if she earns medals in both events.
Selectors were expected to pick one of Wednesday morning's heats swimmers to join Bronte Barratt, Kylie Palmer and Melanie Schlanger in the final, with teenager Brittany Elmslie putting in the best performance.
But they have opted to go with an experienced team and Australia's form swimmer of the meet in Coutts, despite her heavy schedule in London so far.
Coutts won gold as part of the 4x100m freestyle relay team on the opening night of competition before taking bronze in the 100m butterfly and silver in the 200m individual medley.
Australia are strong medal contenders in Wednesday night's final but will have to overcome a powerful US team to challenge for gold.
