Australia's big five on day 13 in Rio

FIVE KEY EVENTS FOR AUSTRALIA ON DAY 13 IN RIO:

CANOE

Men's K2 1000m final (0908 local time, 2208 AEST)

Australians Ken Wallace and Lachlan Tame have set their sights on gold in the final at Lagoa Stadium.

SAILING

470 medal race (1350 local time, 0250 AEST Friday)

Sailors Mat Belcher and Will Ryan are assured of at least a bronze medal but are hunting a silver. Gold isn't impossible, but it's improbable.

DIVING

Women's 10m platform semi-final (1000 local time, 2300 AEST Friday)

Triple Olympian Melissa Wu and Brittany O'Brien contest the 10m platform semi-finals - and hopefully the final later in the day, with Wu ranked fourth entering the semis.

TRIATHLON

Men's triathlon (1100 local time, 0000 AEST Friday)

Aaron Royle is rated the best medal prospect though compatriots Ryan Bailie and Ryan Fisher will also press for top 10 finishes.

ATHLETICS

Men's 1500m semi-final (2055 local time, 0955 AEST Friday)

Ryan Gregson steps out in a semi-final but will likely need a personal best to make the final.
