Anna Meares claimed a golden double as Australia finished the top nation at the UCI Melbourne track cycling World Cup leg on Saturday.
Meares captured the keirin and 500m time trial gold medals as Australia completed the three-day event winning eight of the 17 events at their home leg.
Meares, who won the 500m time trial in the second-fastest time in history at 33.583 seconds, came away with three gold medals at the event following her earlier victory in the sprint.
Lithuanian Simona Krupeckaite holds the 500m time trial world record at 33.296.
"I was really quite worried about the load this evening and once the 500 (time trial) was out the way, I really didn't get the chance to celebrate, I was straight into the mindset of the keirin," Meares said.
"I was tired, I was hurting, but I actually felt half decent."
The keirin win was particularly significant for Meares because she suffered a serious neck injury in a race fall in January last year and it was only the second time she has won a World Cup keirin gold medal.
New Zealand won two gold medals on the final night in the women's team pursuit and men's madison.
The New Zealand team of Kaytee Boyd, Lauren Ellis and Alison Shanks clocked 3:24.771 in beating Britain and Australia in the women's team pursuit, while Marc Ryan and Thomas Scully combined to win the madison from Germany and Ukraine.
The Kiwis finished second overall to Australia in the Melbourne leg with Germany third.
