Australia's big five in Rio on day six

FIVE KEY EVENTS FOR AUSTRALIA ON DAY SIX IN RIO:

SWIMMING

WOMEN'S 100M FREESTYLE FINAL (2318 local, 1218 FRIDAY AEST)

The Campbell sisters go for gold. World record holder Cate is the fastest qualifier in the final and world champion Bronte is fifth quickest.

SWIMMING

MEN'S 200M BACKSTROKE FINAL (2226 local, 1118 FRIDAY AEST)

World champion Mitch Larkin missed out on a medal in the 100m but has said all along he favours the longer race.

ROWING

MEN'S QUAD SCULL FINAL (1012 local, 2312 AEST)

Sasha Belonogoff, Karsten Forsterling, Cameron Girdlestone and James McRae are ignoring the talk that they're hot favourites.

But they've had an extra day to close their ears, with the final rescheduled from Wednesday due to foul weather at Lagoa Stadium.

ROWING

MEN'S PAIR FINAL (1044, 2344 AEST)

Spencer Turrin and Alex Lloyd are hoping for a medal, with New Zealand's Olympic champions Hamish Bond and Eric Murray, who haven't lost in 68 races since 2009, the closest thing to a Rio certainty there is.

CANOEING

WOMEN'S K1 CANOE SLALOM SEMI-FINAL (1315 local, 0215 FRIDAY AEST) AND FINAL (1500 local, 0400 FRIDAY AEST)

Silver medallist in London as an 18-year-old, Jess Fox goes into the semis as one of the favourites for gold.
