Australia's big five in Rio on day seven

FIVE KEY EVENTS FOR AUSTRALIA ON DAY SEVEN IN RIO:

ROWING

Men's fours final (1124 local time, 0024 AEST Saturday)

Shapes as a thrilling match race between the four-time defending champions from Great Britain and the Australian crew of Joshua Dunkley-Smith, Joshua Booth, Will Lockwood and Alexander Hill, who were easily the quickest boat in the semis. Could Australia be about to laud a new Oarsome Foursome?

WOMEN'S SOCCER

AUSTRALIA V BRAZIL (2200, 1100 AEST Saturday)

The Matildas take on the host nation in Belo Horizonte in a rematch of last year's round of 16 clash at the Women's World Cup, which Australia won 1-0. The Brazilian men have struggled through the Olympic group stages, so much so that many local fans have scribbled the name Neymar off their No.10 shirts and replaced it with women's star Marta. The Australian women flogged Zimbabwe 6-1 in their final group game.

CYCLING (1820, 1920 AEST Saturday)

Great Britain are red-hot favourites to win another Ashes-style challenge after dominating the heats of the men's team pursuit. The Brits looked unstoppable in posting a sizzling time of three minutes and 51.943 seconds. Australia (3:55.606) were the third-fastest at the velodrome and will take on Denmark for a spot in the gold medal final.

ATHLETICS

MEN'S 20KM WALK FINAL (1430, 0330 AEST Saturday)

With Jared Tallent sitting this event out to protect a sore hamstring, all the Australian focus will be on young Dane Bird-Smith, who rates himself a genuine medal shot. Bird-Smith is coached by his father David, a two-time walking Olympian.

SHOOTING

MEN'S 50M RIFLE PRONE (0900, 2200 AEST Saturday)

Even at 54, Warren Potent remains a legitimate contender in the event where he won Australia's most recent men's shooting medal - a bronze in Beijing eight years ago.
