The broadcaster took the gold medal for Best Social Media Content/Production for its "From Little Things, Big Things Grow #HomeGames" campaign.

The two-minute video documented how Australia's athletes inspired children watching from home to take up sport.

It beat content from BBC Sport and SBS, who took silver and bronze, respectively.

The feature on BMX siblings Kai and Saya Sakakibara won the network the silver medal for Best Athlete Profile, beaten only by Brazilian station TV Globo's profile on skateboarding sensation Rayssa Leal.

MARCA Claro was awarded bronze for its piece on Argentine judoka Paula Pareto.

Channel Seven's final medal was bronze in the Best Olympic Feature/Documentary for its Jess Fox Gold Medal Split Screen.

All of Channel Seven's segments were produced by Nick Barrow and directed by Lewis Martin.

AOC chief executive Matt Carroll claims Australians were able to appreciate the efforts of the country's athletes in record numbers, thanks to the coverage.

"Broadcast figures were up 71% on Rio 2016, while 4.74 billion minutes were streamed on 7plus through its 40 digital channels," said Carroll.

"The depth and breadth of the coverage was outstanding.

"For our Australian broadcaster to be successful in three of the 12 categories speaks volumes for the quality of the Channel Seven production team.

"Our athletes and their stories certainly connected with the community during the Games. 

"Channel Seven brought those stories to life brilliantly.

"The three medals are richly deserved."

The medallists were selected by an international jury headed by IOC member Anant Singh, a leading film and media professional, chair of the IOC Communications Commission and a member of the IOC's Olympic Channel Commission and the Digital & Technology Commission.

Awards were handed out at the International Olympic Committee’s headquarters, Olympic House, in Lausanne in Switzerland.
