Athletics Australia have continued their conservative approach to their Olympic team selection.
Only athletes who have achieved an A-qualifying standard have been selected in the team so far.
No marathon runners have been added to the squad which will compete at the 2012 London Games from 27 July to 12 August.
Lisa Weightman is widely expected to represent Australia in the Women’s Marathon event on August 5. Weightman won bronze at the 2010 Delhi Commonwealth Games and is in good form heading into the Games.
Athletics Australia must submit their team by the June 11 cut-off.
