Britain's lead almost disappears down the plughole within moments.

Australia go back on the attack, winning a penalty corner. Big chance. Georgina Morgan's shot beats British keeper Maddie Hinch - but they are saved by the frame of the goal.

We are life's winners, Adam. The best thing? There's two more weeks of wall-to-wall sport.

Just about an hour to go until the swimming finals start...

Breakthrough! Great Britain have been very lively in the past few minutes - and now they have been rewarded. Lily Owsley hooks in from close range a few minutes before half-time. What a time to score.

Great Britain's Paul Drinkhall breezes into the second round as he beats Aleksandar Karakasevic 4-1.

Great Britain reached Monday's Olympic gymnastics men's team final with an impressive display in qualification.

They were fifth overall with 2012 champions China compiling the best overall score followed by USA, Russia and Japan.

Britons Nile Wilson, Max Whitlock and Brinn Bevan all qualified for the individual all-around final which is on Wednesday.

Whitlock also qualified for the floor and pommel finals, Kristian Thomas made the floor final, Louis Smith is in the pommel final and Wilson will be in the high bar final.

Great Britain, who won bronze at London 2012 you will remember, are camped in the Australia half. Can they make a breakthrough? Not yet. 

The Hockeyroos (possibly the worst nickname in sport) bounce back, British keeper Maddie Hinch needing to be alert to block.

David: Hockey must be exhausting to play - all the players seem to have to run up & down the pitch very quickly very often

Good call. What's the toughest Olympic event, physically? Got to be rowing hasn't it?

I couldn't do any of them, obviously, but the rowers always look absolutely finished at the end of the race...

The game's first penalty corner goes to Australia and Crista Cullen charges it down like a bull to take the ball full in the stomach. She hits the deck. That was like something from a Game of Thrones battle scene.

"Let's go GB, let's go" is the chant from a portion of this crowd. It sounds like friends and family of players as they are relentless in their noise.

Australia the better side as that quarter ends. Maddie Hinch has made a handful of saves for Britain.

Remember, it's four quarters and not two halves now in hockey at the Olympics so the added intensity may prove sapping.

"It has been an absorbing first quarter. There hasn't been any goals but both teams have come to win three points. It has not been cagey. Australia have arguably had the better chances but it has been positive for Great Britain." 

USA are closing in on victory in their Group A match with China. The 14-times Olympic gold medallists lead 107-61 with two minutes left in the fourth quarter.

Yep, this one is going the distance. Belgium's Kirsten Flipkens levels the match against American veteran Venus Williams with a dominant performance in the second set.

That doesn't stop the Americans in the Rio crowd enjoying themselves. Plenty of Stars and Stripes flag waving and hip wiggling from the Venus fans at the changeover.

It's heating up in an epic final, as Beatriz Piron Candelario is the current leader in the women's 48 KG weightlifting.

 They are currently lifting more than double their own bodyweight. Frightening stuff. 

Follow it here. 

Great Britain's Paul Drinkhall breezes into the second round as he beats Aleksandar Karakasevic 4-1. Drinkhall had lost the first game but fought back strongly to progress.

"I think it's potentially dangerous play. It hit Crista Cullen above the knee which is given to the defender. Australia are building momentum now."
