That is almost twice as many as competed for the nation at the Lillehammer 2016.

The Australian Olympic Committee (AOC) has announced that 20 athletes from freestyle skiing, snowboard, cross-country and Alpine skiing will join the 13 from biathlon, ice hockey and short track speed skating who were named last week.

"I’m proud to announce the 33 athletes to represent Australia at the Lausanne 2020 Winter Youth Olympic Games," ustralian Chef de Mission and Vancouver 2010 Winter Olympian, Ramone Cooper, said.

"To be chosen to represent your nation in any competition is a proud achievement and to compete in the green and gold with the Olympic rings on your uniform is a special experience.

"I congratulate not just the athletes but coaches, support staff, National Federations, families and support for this outstanding achievement.

"My goal for this team is to encourage an environment that supports athletes to have their best performance on the right day, and most importantly to have an experience that leads to growth and development as elite athletes and positive ambassadors within their communities.

"The YOG is the ultimate international multi-sport event for emerging elite athletes, and I am looking forward to seeing the team come together in Lausanne."

The third edition of the Winter YOG will feature a two-wave competition format, an innovative concept designed to increase hosting capacities with each wave of athletes having a shorter stay in the village.

The first wave of competition will take place from January 9 to 15, with the second wave starting on January 16 until the closing ceremony on January 22.

 "The two-wave concept for Lausanne 2020 will provide us the opportunity to showcase the great work that our NFs are doing in growing the depth and improving the quality of athlete pathways, which has allowed us to send our largest ever Winter YOG Team to Lausanne," Cooper added.

"Our team of 33 athletes is almost double that of the 17 athletes who competed at Lillehammer in 2016.

"This reflects the growth of winter sport in Australia and the elite level of our junior athletes, competing against the best in the world in their age group."

Mia Rennie, Abi Harrigan and Gus Broerson will represent Australia in freestyle skiing, with each athlete competing in three different freestyle events; halfpipe, slopestyle and big air.

"I'm incredibly honoured to be selected for the Youth Olympics, it was a goal I set two years ago, and it feels fantastic,”"16-year-old Rennie said.
