Australian under-17 representative Jason Tomane has joined the Brumbies' pre-season training program and the talented back is on track to be a star of the future.

The teenager has been a guest at Brumbies' sessions to get fit and work with the team while some players are out injured.

Joseph Tomane is proof of how Jake White and his coaching staff can accelerate a player's development.

The former NRL centre arrived in Canberra hoping to secure a spot on the Brumbies' bench, but experienced a rapid rise into the starting XV and eventually the Wallabies.

Now it's his brother's turn to impress. Jason Tomane has impressed in the junior rugby ranks for Marsden High School and has been a standout for the Sunnybank Rugby Club in Queensland.

His involvement at Brumbies headquarters is limited to conditioning training and occasional contact work. But after impressing national selectors this year to earn a place in the Australian merit under-17 squad, Sunnybank development manager Harry Norris backed Jason to follow his brother.

Joseph has built his game on being a powerful outside back with speed to burn.

Jason - while still growing - has the same attributes and the talent to achieve his goals.

''He's a big strong boy and he's just going to get bigger and stronger,'' Norris said of Jason.

''He and Joe are knocked out of the same mould, they're robust, big and powerful.

''Running around with the Brumbies has to be good for his ability to set himself goals training against people better than him so he can keep improving.''

Until he's ready to rise into the Super Rugby ranks, Jason will be taking inspiration from Joseph's superb transition to rugby union.

The block-busting winger has almost returned to full training after an ankle injury cut short the end of his first season with the Brumbies and has hopes of joining the Wallabies for their end of year Tests.

Tomane - a former Melbourne Storm and Gold Coast Titans centre - feels more at home in Canberra now.

He has established himself as a dangerous attacking weapon for the Brumbies and made his Test debut in a year he had planned for ''development''.

The 22-year-old is determined to continue his improvement next season and force his way back into Wallabies contention.

Tomane made his Test debut against Scotland before injuring his ankle. ''I definitely want to get back to that Wallabies level and I'm working hard to make sure I improve on last season,'' Tomane said.

''I just want to go out and make sure I don't suffer from second-year syndrome and get back to where I was. The way to approach is to focus that you've got to produce because everyone will improve, but you don't drain yourself with killer pressure and then you'll have a killer year.''

The Brumbies have added strong depth to their outside back ranks for the 2013 season. Tomane and Henry Speight occupied the wing spots for much of last season but Clyde Rathbone's return adds more punch with Tevita Kuridrani also impressing at training.
