ACT Brumbies winger Henry Speight has put his Wallabies dream "on the backburner" to focus on Super Rugby success, determined to continue his scintillating form to earn another crack at winning a championship.

Speight was one of 11 Brumbies included in the Wallabies' 32-man squad for the Rugby Championship, with coach Ewen McKenzie opting to add him to the roster despite the Fijian-born flyer not being available for selection until September 11.

McKenzie is bursting with excitement at the prospect of injecting Speight into the international arena.

But first Speight is channelling all of his energy into the Brumbies' semi-final clash against the NSW Waratahs in Sydney on Saturday night, refusing to start dreaming of a Wallabies debut as he waits for his drawn-out eligibility saga to be finished in two months.

The 26-year-old is expected to be parachuted into the line-up for the Test against Argentina on September 13 and he's making an undeniable case for a call up with his outstanding Brumbies performances.

"It's a massive honour to be in the squad ... but this weekend there is a job needs to be done and I'm focused on that," Speight said.

"I've shelved [thoughts of Wallabies] and put it in the back of my head. If I circled [September 11] then it was going to be the longest few months, it was good to put it on the backburner.

"It's good to be able to focus on Brumbies and my motivation has been just the team doing well. I'm really enjoying getting the ball out wide and having fun. I owe it all to Matty Toomua and Christian [Lealiifano] for spreading the ball. I owe them a coffee or two."

Speight is the feel-good story of Australian rugby, with the sport yearning for a hero after Nick "The Honey Badger" Cummins quit his ARU contract to move his career to Japan.

Known as the Brumbies' ''bro with the fro'', Speight has spent the past four seasons in Canberra. But the IRB delayed his Australian eligibility because of a brief return to play for Waikato in New Zealand at the end of 2011.

The Department of Immigration is refusing to allow his brother Jerry and sister Davila into Australia to watch him play because the pair have been deemed a risk of becoming asylum seekers.

The Brumbies' win against the Waikato Chiefs last week was the first time any of his siblings had been able to watch him play in Australia, with older brother Sam gaining entry to the country because he's a British national.

Speight's uncle is George Speight, the Fijian coup leader serving life in jail. His late grandfather, Josefa Iloilo, is a former Fiji president.

Family is Speight's motivation for success, dedicating every performance to them. Even his afro has a family link, after he started growing it for 100 nights as part of Fijian tradition to honour the memory of his cousin, Malachi, who lost his battle with cancer in 2013.

Speight will miss the first three Rugby Championship Tests before being available for selection.

"He can play powerfully, he's got speed, he can evade. He's not just confrontational, I like that," McKenzie said.

"But I also like that off the field he's softly spoken but clearly intelligent. He has a lot of allies, a lot of people speak very highly of him. I can see why he can bring out the best in people around him.

"There's a crowd favourite departing in Nick Cummins, but a real interesting guy coming in with Henry Speight ... I didn't know much about him until June and I was very impressed with him."

Speight is working with the Brumbies and the ARU to have his family present at his Test debut.

Davila and Jerry have had two visa applications denied by immigration. Speight has given written evidence that his brother and sister will return to Fiji after a brief visit so that he can show them his new home.

"Everything I do, I do it for my family. They're my motivation," Speight said.

"To be able to do it for them makes it extra special, I'm blessed and lucky to have a great family. The whole Brumbies organisation has been my family for the past four years in Canberra ... I play for my family back home and all Canberrans."
