Australia's victorious Women's 4x400m Relay team.
In a night of upsets, Australia has won gold in both the Men's and Women's 4x400m Relays.
Jana Pittman put the Australian women in front on the first lap, with Jamaica soon after pushing forward to take a clear lead of more than five metres.
But gold slipped from the Jamaicans' hands during the baton exchange between Novlene Williams and Shellene Williams. The team admirably continued to finish fourth.
England crossed the line first, but was later disqualified for running outside their lane - giving the gold medal to Australia, with a winning time of 3:28.66.
"I'm not complaining about the way we won," said Australian runner Tamsyn Lewis."Relays have rules, and rules are rules.
"I was just trying to chase the girl in front of me. There was a lot of rough stuff happening ahead of me."
In the final results, India won the silver medal and Nigeria the bronze. Jamaica finished fourth, Papua New Guinea, fifth and South Africa was also disqualified. Sierra Leone did not start.
In the men's event, Australia had a narrow lead at the first changeover but then extended their lead in the next three legs of the race to win in a time of 3:00.93.
In the last metres of the race, South African Louis Van Zyl, winner of the Men's 400m Hurdles, edged past the competitors from Jamaica, England and Nigeria to finish second. A desperate lunge from Jamaica saw them take bronze.
Further back in the field, Sri Lanka finished sixth, Trinidad & Tobago were disqualified and the Bahamas did not finish.
