The 2020 Tokyo Olympics opening ceremony kicks off this Friday July 23 at 9pm AEST, a year late as a result of COVID-19.

Australia will be represented in all 33 Olympic sports this year, all of which will be broadcast on Channel Seven.

Sydney, Melbourne, Canberra, Brisbane and Hobart are one hour ahead of Tokyo which means Australians won't have to stay up late to watch most events.

And despite the controversy surrounding the games, we've never needed the Olympics more.

Here are five athletes you'll no doubt be hearing a lot about in the next two weeks.

Kaylee McKeown

Kaylee McKeown is one of Australia's biggest Olympic stars this year, after breaking the world record for 100m backstroke by more than a tenth of a second in the 2021 Australian Olympic trials.

Her father, Sholto, died of brain cancer in August last year. Mckeown has called the postponement of the Olympics a "blessing in disguise" as she was able to spend more time with him before his passing.

“It’s made me realise how much life is worth living,” McKeown told the Sydney Morning Herald.

“I just take every day as it comes and I honestly think that’s the main reason I’m swimming as well as I am. There’s no point in wasting the opportunities that you have in life.

“He’s my big inspiration and I use him in the last 50 of the race to help me cross the line because I know he is there.”

The 20-year-old will be competing in the women's 100m backstroke on Sunday, July 25 at 8.14pm, and the women's 200m backstroke on Thursday, July 29 at 9:13pm.

Patty Mills

Patty Mills is no stranger to the Olympics, with Tokyo marking his fourth games.

This year though, the 32-year-old Boomers basketball captain will be the first Indigenous flag bearer for Australia, alongside swimmer Cate Campbell, who will be the first female swimmer with the role.

On being asked to be a flag bearer, Mills told the ABC: "It was an easy decision. I am very proud of who I am...

"At the end of the day I imagine little girls and little boys, whether they are at home or at school... I can picture them and what they might feel or how they'll react when they see someone like me being a representative of them.

"That's what it's all about, right? Having the next generation come up and be true to themselves, proud of who they are, proud of their identity, and to wear that on their chests... that can help them achieve their dreams."

Mills is one of Australia's top basketballers having been drafted to the NBA in 2009, and having competed in the Olympics since Beijing in 2008.

You can watch him on Sunday, July 25 at 6.20pm as Australia plays Nigeria, Wednesday, July 28 at 6.20pm as Australia takes on Italy and again on Saturday, July 31 in Australia plays Germany.
