Australia has soared to the men's 4000m team pursuit world record in front of an electric crowd at the Anna Meares Velodrome, becoming the first country to post a sub three minute 50 second ride in the history of the event.
Earlier in the day, the quartert of Alex Porter, Jordan Kerby, Leigh Howard and Sam Welsford qualified fastest in 3mins 52.041.
A tactical move from the team saw teenager Kelland O’Brien come in for Kerby, with the team scorching the track in a world record time of 3 minutes 49.804 seconds, shaving nearly half a second off the record held by Great Britain set at the Rio 2016 Olympic Games.
It is the first time since 2004 that Australia has held the world record.

I'm over the moon with excitement. We're in our home country. That is what dreams are made of. This is what we strive for every day.
This is a dream come true. We've had our eye on the medal for such a long time, and to go under 3.50 - for that to happen is unreal.

It overwhelms me having my parents and sisters and all my family here, it's something really special and I definitely shed a tear.
A few more years (towards Tokyo) is going to be hard to stay up in the top end but the depth in Australian cycling is amazing, the culture is amazing and I'm so proud to be part of the team, and hopefully in the next few years we can step up again and show the world what our country is all about."
Leigh Howard (VIC)
It is a special moment. it was a big decision for me to give up the road and come back to the track, but I had a fair bit of self belief and saw it was such a special group of guys and I wanted to be part of it.
This guy next to me (Welsford) is an absolute machine, just to follow his wheel is a tough ask. There's definitely been some big changes since he's come on board and we've gone faster, it's as simple as that.
3:50, it's just evolution and we're not sure what the next mark is but we'll just keep striving. That's the big question but we've got to find that way.
