World number eight Kelsey Cottrell suffered a similar fate during round five, losing her first match to Fiji's Litia Tikoisuva 13-21.
Cottrell found herself trailing Tikoisuva for all but three ends of the match and won't have a chance to make amends till tomorrow's round seven encounter against USA's Dee McSparran, due to a whole section bye in round six.
While in the women's fours, Natasha Van Eldik, Rebecca Quail, Lynsey Armitage and Karen Murphy have jumped up to first position on their section with a comprehensive victory over Samoa 35-6, and have a section wide by this afternoon.
Australia has rebounded strongly from this morning’s shock defeats at the Asia Pacific Championships and remain in contention to advance directly to the semi-finals across the board.
Both Australian female sides, the singles and fours, enjoyed a respite in the afternoon session and will now face USA and Japan respectively in their final round-robin matches before post-sectional games are held on Thursday.
