Anna Meares turned the tables on her great British rival Victoria Pendleton on her way to winning two gold medals in one day at the track cycling World Cup round in Manchester.
Competing internationally for the first time since last year's Beijing Games, the Australian clocked 33.632 seconds to win the 500m time trial by two tenths of a second from Olympic champion Pendleton.
She then paired with Kaarle McCulloch to win a second gold in the team sprint.
"It's nice to get a good ride as it's been a while since I've raced internationally," said Meares, who took silver behind Pendeleton in the sprint at the Beijing Olympics.
"I'm really happy and the more this tournament has moved on the more comfortable I've been getting."
"It's been great but I've done a lot of work to get here. I wanted to start the season well and I've done that for sure."
The 26-year-old Queenslander joined McCulloch to post the fastest time in qualifying for the team sprint (33.363 secs) before defeating Dutch pair Yvonne Hijgenaar and Willy Kanis in the gold medal race.
In the medal round Meares was the only rider to post a sub-19 second first lap, clocking 18.754sec and giving McCulloch a perfect platform to bring home the win with a final time of 33.653sec, half a second better than the Dutch (34.014sec).
Germany defeated Great Britain for the bronze medal.
"I've been struggling a bit with sickness which has affected my preparation so I'm really pleased we got the win," said McCulloch.
In the women's 3km individual pursuit West Australian Josephine Tomic couldn't match the experience of Britain's Wendy Houvenhagel in the gold medal race.
Houvenhagel was almost ten seconds faster in the qualifying round than Tomic and in the final went out hard, overtaking Tomic with a few laps remaining.
"I was trying to do a personal best but that didn't happen," said 20-year-old Tomic who was the junior world champion in the two kilometre distance in 2007.
"It's only my second year at elite level and Wendy was just too good for me."
Dutch rider Vera Koedoorer claimed the bronze medal.
Victoria's Shane Perkins, 22, qualified fourth fastest for the men's sprint and won his way through to a bronze medal ride against Jason Kenny where the British rider proved too strong defeating Perkins in two straight heats.
Canberra's Dan Ellis, 21, drew the short straw with his seeding coming up against an unbeatable Sir Chris Hoy in the quarter finals.
Hoy then made short work of Perkins in the semi-final before easily beating compatriot Matthew Crampton for the gold medal, giving the home team a clean sweep of the sprint podium.
In the madison, Australia's Leigh Howard and Glenn O'Shea, both 20, won the first sprint but couldn't snag any more points and finished in eighth place.
No laps were taken in the race which was won by Belgians Kenny De Ketele and Tim Mertens who collected 17 points, one more than Germany's Roger Kluge and Robert Bartko. Russia's Sergey and Alexey Shmidt claimed bronze with 11 points.
Yesterday's scratch race winner Belinda Goss, 25, had a bumpy ride into the points race final after crashing with three other riders in her qualifying heat.
But the Tasmanian rejoined the race to earn a start in the medal final. Goss scored seven points to finish fifth with the victory going to Great Britain's Lizzie Armitstead who amassed 16 points.
There is one day of competition remaining in Manchester before attention turns to Melbourne for the next round later this month.
