Australia's big five in Rio

FIVE KEY EVENTS FOR AUSTRALIA ON DAY THREE IN RIO

SWIMMING

WOMEN'S 100M BACKSTROKE FINAL (2230 local time, 1130 Monday AEST)

Emily Seebohm has only qualified seventh fastest for the final in the event where she had her Olympic dreams dashed four years ago in London. Can she lift with the gold medal on the line? Countrywoman Maddie Wilson could also be in the medals hunt.

SWIMMING

MEN'S 100M BACKSTROKE FINAL (2238, 1138 Monday AEST)

Eight minutes after his partner Seebohm goes for gold in the women's 100m backstroke, double world champion Mitch Larkin gets his shot at glory in the men's race.

MEN'S BASKETBALL

AUSTRALIA V SERBIA (1415, 0315 Tuesday AEST)

The winner of this match will be in the box seat to finish second in Group A, which would likely mean avoiding the star-studded Americans in the knockout stage until the gold medal match. Point guard Milos Teodosic is the key man for the Serbs.

WOMEN'S RUGBY SEMI-FINALS AND FINAL

AUSTRALIA V CANADA IN SEMI (1430, 0330 Tuesday AEST) FINAL (1900, 0800 Tuesday AEST)

Australia arrived in Brazil as the red-hot favourites to win the first-ever Olympic women's rugby gold and while there was a hiccup along the way with a draw against the US they're still a big show of winning here.

WOMEN'S HOCKEY

AUSTRALIA V UNITED STATES (1000, 2300)

After dropping their opening match to Great Britain, this shapes as a must-win clash for the Hockeyroos. Most Americans favour the version of hockey which is played on ice, but the US women's field hockey team have made a flying start in Rio, upsetting Argentina 2-1.
