Lauren Perry and Josh Duffy defending national track titles

The perennial Christmas carnival contenders are both based in Adelaide and members of Australia's podium potential academy which aims to provide a pathway into the national senior team.

Tasmanian Institute of Sport cycling coach Matthew Gilmore said Perry, 24, and Duffy, 20, have settled in well and are ready for a hectic schedule on the Anna Meares Velodrome from Wednesday to Sunday.

"They both get on well with the group there. It's been an easy transition and they are certainly enjoying it," he said.

"They had trials last week in Adelaide and both are going really well.

"Lauren has a fair workload, she's basically racing in everything. She wants to defend her scratch race title and get a good individual pursuit in.

"Josh is hoping to do a good 1km time trial with the scratch and points race also important to him."

The senior track team, including Perth's Rio Olympian Georgia Baker, are not competing in Brisbane as they finalise preparations for July's rescheduled Tokyo Games.

Gilmore said this changes the dynamic for the full schedule of elite races.

"Not having the big guns here means a lot of the young kids are prepared to take more chances which makes for really good racing and can become quite unpredictable and a bit of a lottery."

Launceston's Hamish McKenzie will join North-West Coast trio Dalton Stretton, Jack Menzies and Will Eaves in the under-19 races.

"It's the first time we've had an under-19 team pursuit for a number of years and that's really encouraging.

"Hamish and Will have come up from under-17s where they won the virtual national championships team pursuit and the other two are second-year under-19s so it will be interesting to see how they go.

"It's unusual for us not to have more females and that's an area we will need to look at in the next 12 months, but athletes don't grow on trees."
