The 18-year-old was yesterday named alongside fellow multiple junior world champion Alexandra Manly, of South Australia, as joining ORICA-AIS for 2015.

The move follows considerable planning with the national track cycling team and will see Stewart reunited with her former Tasmanian Institute of Sport coach Gene Bates, who is now the ORICA-AIS sport director.

Stewart, who won the under-19 time trial at this year's road world championships in Spain after double gold at the track world titles in Korea, said she would be proud to make her team debut at the Stan Siejka Launceston Cycling Classic on Sunday.

"I am really excited to pull on the ORICA-AIS kit in front of all my family and friends at home," she said.

"It's awesome that the race is in Tassie and I am so excited to get out there and give as much as I can.

"I am sure I will be playing a team role and hopefully I can do as much as I can. I have just had a pretty hard training block and haven't raced in a few months so it will be interesting to see how I am going and I'll give it a real red-hot crack."

Stewart, who will also grace this year's Christmas carnivals series, said she was excited by the next 12 months.

"I have a really exciting year ahead. I will be pretty busy on the road and the track but it will be good to mix things up a bit and keep it exciting.

"Going over to Europe I am just trying to learn as much as I can. I know I'm only in the early stages of my career at the moment and I am going over there so young, so I'm happy just to learn as much as I can from the girls with a bit more experience than me."

Bates said the dual signings were a huge boost to the team's European debut and longer-term to Australia's Olympic hopes.

"It was felt, as young developing riders with the national track program, that both Alex and Macey would benefit greatly from a measured exposure to road racing and that ORICA-AIS provides the ideal environment to learn the ropes of road racing," Bates said.

"Obviously we were very keen to offer this assistance as we believe both riders to be very capable roadies in the future, and we realise that this will enhance their abilities on the track and their prospects of contributing to a medal performance for Australia in Rio.

"We are looking forward to this season, which in a way kicks off this weekend at the Tasmanian criterium."

Stewart and Manly, also 18, join 10 full-time riders who will gather for training camps in Nagambie and Bright before a January schedule incorporating the Bay Cycling Classic, national road titles and Cadel Evans Great Ocean Road Race, all in Victoria, plus the Women's Tour in South Australia.
