8:55pm - That's all, folks...for today
It's been a big day of Sevens, but this is just the beginning. Saturday brings Cup quarter-finals and semi-finals, and the remainder of the men's pool matches on the biggest day of the three.
Japan beating England is out pick for the biggest shock of the day, but the Aussie men toppling the USA was a nice way to cap off the opening day of their home tournament.
Two days to go, and we'll have you covered with every match.
851pm - Men's Pool D - Canada 5 - Scotland 52
Scotland are the final victors on the opening day of the Sydney 7s, beating out Canada, 47-5.
The Scots burst out of the blocks, shooting out to a 21-5 half-time lead, and their momentum only heightened after the break, piling on the tries.
A Max McFarland hat-trick led the way for the Scots, while a Canada yellow card did their chances no favours when they were already under the pump.
Tries for Jamie Farndale, Gavin Lowe and Glenn Bryce contributed to the blowout, before Alec Coombes sealed the victory to end day one.
8:31pm - Men's Pool D - Australia 26 - USA 19
Australia's men's Sevens have edged out the USA in their opening match of the Sydney 7s, 26-19.
The Aussie men have performed beyond expectation in every Sydney World Series leg and they looked a force to be reckoned with again on Friday night.
The night started perfectly for the Australians, with Lachie Anderson breaking the line and handing off to Boyd Killingworth to finish off in the third minute.
Rookie Ben O'Donnell made it two for the Aussies not long after, slipping cleverly through defence, before John Porch showed his pace, streaking away from the American defenders to make it 19-0.
The challenge for the men is to take their momentum through to day two, where they will face Scotland and Canada in a bid for a quarter-final spot.
Super speedster Perry Baker left the Aussies in his wake to hit back in the second half and Martin Iosefo took advantage of a defensive miscommunication to narrow the margin to just five.
A valiant chase from Lewis Holland wasn't enough to stop Ben Pinkelman from levelling the scores in the 11th minute, but Tim Anstee put the Aussies back in the box seat, with a blistering 75-metre run.
When Carlin Isles, the only man possibly faster than Baker in the USA side, found the ball after the final whistle, panic could have ensued, but the Aussies' defence stifled the sprinter and they held on for a surprise win.
Australia's next pool match is against Canada on Saturday at 5:15pm AEDT.
8:05pm - Men's Pool A - New Zealand 54 - Russia 0
New Zealand won the Cape Town tournament and they've picked up where they left off on arrival in Sydney.
Holding a 33-0 lead at half-time, the Kiwis romped home in the second half over Russia, breaking the 50-point barrier and putting themselves well on top of the pack early.
The Aussies are up next. Can they start their Sydney tournament on a high?
8pm - Aussie men have arrived
The Aussie men will be in action in 12 minutes, against the USA, and they're well and truly in the building.

England were highly favoured heading into this one and they were never really troubled by a Spanish side that put up a fight without ever looking particularly threatening.
5:40pm - Women's Pool A - Australia 43 France 0
Australia are yet to concede a point at the Sydney Sevens, flogging France to go top of Pool A.
Emilee Cherry hadn't tasted game time so far today but she turned her first touch into gold, scoring a long range effort inside the first minute.
It was a Cherry offload that set up Australia's second, Alicia Quirk the beneficiary of her slick hands.It was Charlotte Caslick's turn next, slicing the line in similar fashion to her try in the second match - throwing a dummy and showing quick feet to beat the French defence.
Ellia Green then scored as the final siren sounded, opening up a big 24-0 lead at the break.
Green added a second and third in the second term, with Cherry also nabbing a brace as the Australians ran in tries at will.
5:20pm - NZ flying on day one
We had a chat to Portia Woodman after she scored 10 tries on day one.
Black Ferns assistant coach Cory Sweeney was very impressed with his team's return to the field after a disappointing stint in Dubai.
"Yeah, we are really happy, coming off Dubai was a little disappointing so it was important for us today, day one we had a few learnings today and we're really happy with the girls - they performed really well," he said.

12:45pm - Aussies open campaign with a win
ICYMI, here's a full match report following Australia's opening pool match win over Spain and some highlights for your viewing pleasure.
See what Emma Sykes had to say, too.
12:05pm - Women's Pool A - Australia 29 Spain 0
Emma Sykes was the star of the show early, crossing for the first try of the match before converting from close to the sideline.
Charlotte Caslick matched her fellow playmaker's efforts two minutes later, winning a penalty over the ball at the breakdown and showing brilliant initiative to quickly tap and scoot over for Australia's second.
Ellia Green turned her first touch into gold, cleaning up a Sykes cutout pass, beating two defenders and touching down to mark a triumphant return to the field.That took the score to 19-0 at the break and it was Sykes that crossed again halfway through the second term.
Vani Pelite, who starred in Dubai, was next to score, using the beacon of Green down the left hand sideline to leave the Spanish defenders clutching at air as she sliced the line to score the final five points of the match.
Australia's play was good but certainly not great, lacking the fluidity in attack that was there throughout the finals in Dubai.
That may be nerves and it may be rust but it will be something for coach Tim Walsh to ponder as they prepare for their second match of the afternoon, against PNG at 2:34pm AEDT.
11:45am - Women's Pool A - France 50 PNG 0
France set up shop inside PNG territory for the entire first half and scored three tries in that term, hardly getting out of first gear.
