SYDNEY - Australian Olympic Committee (AOC) launched the "Have a Go" campaign on Olympic Day, delivering a message that "great things happen when you have a go" to all Australians.

The campaign will run from June 23 through the duration of the Tokyo Olympic Games. Aiming to promote the benefits of being healthy and active, regardless of location, age or ability, the campaign will provide more information about Olympic sports and local clubs to encourage people to start playing Olympic sports from the grassroots level.

The campaign will also offer a "HaveAGo kit," including sports infographics, activity calendars and certificates, to encourage kids to have a go at Olympic sports and celebrate the Olympic Games at school.

AOC CEO Matt Carroll said this campaign is crucial for the development of the nation.

"It's about bringing communities together, creating vital connections and being inclusive; this is something that deserves real celebration," Carroll said.

June 23 is also the International Olympic Day, as athletes across the globe prepare to gather in Tokyo in exactly a month for the opening ceremony of the Tokyo Olympic Games.

As preparations for the Games continue, Australia's team selections have ramped up, with 273 athletes selected so far. The AOC estimates that there will be between 450-490 athletes selected for the Games eventually.
