South Africa will play Australia in the quarter-finals of the Olympic Sevens in Rio on Wednesday.

The game, which kicks off at 11:30pm SA time, is a rematch of the Pool B clash, which Australia won 12-5.

Meanwhile, New Zealand scraped into the quarter-finals when the USA suffered a five-point defeat to Fiji. The Americans scored a late try, but missed the conversion that would have seen them qualify at the Kiwis' expense.

New Zealand will now play Fiji in the quarter-finals, with Japan taking on France and Great Britain up against Argentina.

Olympic quarter-finals (SA times):

Fiji vs New Zealand (22:00)
Japan vs France (22:30)
Great Britain vs Argentina (23:00)
South Africa vs Australia (23:30)
