Australia has made the perfect start to the Tokyo Paralympics, winning the first two gold medals of the Games.
Track cyclist Paige Greco broke her own world record in the C3 3000m individual pursuit at the Izu Velodrome and a few minutes later, teammate Emily Petricola lapped American rival Shawn Morelli to take out the C4 3000m pursuit.
Compatriot Meg Lemon lost her C4 pursuit bronze medal ride-off to Canadian Shawn Keely.
Greco, 24, easily beat China's Wang Xiaomei in their gold medal ride-off on Wednesday.
The Adelaide cyclist, who has cerebral palsy, clocked three minutes 50.815 seconds and Wang rode 3:54.975.
Greco also broke her own world record earlier on Wednesday when she qualified fastest in 3:52.283.
Petricola made a shaky start against Morelli and looked in trouble when she was .951 of a second down after the first lap.
But the 41-year-old from Queensland, who was diagnosed with multiple sclerosis 14 years ago, then dominated their ride-off and caught Morelli well inside the last kilometre.
Petricola also broke her own world record when she qualified fastest in 3:38.061.

Lemon trailled early against Keely and could not pull back the deficit, losing by more than a second.
All three Australians are making their Paralympic debuts while Greco and Petricola came into the Games as defending world champions in their individual pursuit categories.
More gold for Australia in the pool
Later on Wednesday, Will Martin broke the Paralympic record and Lakeisha Patterson held off a fierce challenge in the pool to continue Australia's outstanding start at the Tokyo Games.
Martin and Patterson won the first two swimming gold medals at the Games, taking out the S9 400m freestyle events on Wednesday night at the Tokyo Aquatics Centre.
But not everything went to plan for Australia on day one - the Steelers' shock loss to Denmark put an early dent in their quest for a third-straight wheelchair rugby gold medal.
Martin stunned his rivals in the 400m freestyle, going out fast in the finals taking more than seven seconds off his heat time.
The 20-year-old Games debutant from Queensland won in a Games record time of four minutes 10.25 seconds, beating Ugo Didier of France by 1.08 seconds.
Sixteen-year-old Australian Alexander Tuckfield won the bronze and compatriot Brenden Hall, the world record holder, was a surprise fourth.
Patterson also took the early lead in her 400 final as six-time Australian gold medallist Ellie Cole dropped off the pace.
It came down to Patterson and Hungarian Zsofia Konkoly, who briefly took the lead on the last lap.

But Patterson rallied to touch the wall first in 4:36.68 seconds, just .08 of a second ahead of Konkoly.
Ben Hance won bronze in the S14 100m butterfly, while Valeriia Shabalina's world record denied Australian pair Paige Leonhardt and Ruby Storm in their S14 100m butterfly final.
The Russian clocked 1:03.59 to beat Leonhardt by 1.89 seconds and Storm was 2.91 seconds off the pace for the bronze.
