The overlooked Brumby starred in Canberra's 47-22 triumph over Melbourne Rising on Saturday, setting up two tries and scoring one of his own at Box Hill.

The strong performance comes after Pulu's heartbreaking omission from the Wallabies' World Cup squad, who kickoff their title campaign next month.

Pulu saw the Vikings' opening NRC clash as a chance to prove himself as he comes to grips with his Wallabies exclusion.

"It was disappointing with everything that was going on," Pulu said.

"Just being able to come out, play footy again and getting among the boys here was one of my bigger goals coming into the NRC season. Just being able to prove myself."

The 30-year-old left the Waikato Chiefs at the end of last year to pursue international rugby ambitions with the Wallabies.

The flying winger has since been on Michael Cheika's radar, attending multiple training camps and World Cup-planning sessions over the year.

"I've done a lot of work outside training, having been involved with a couple of camps," Pulu said.

"For me, it was to come out, do my job and hopefully get over that touch line which is what I did [on Saturday]."

Pulu is one of several players who can use the Vikings campaign as a chance to prove a point to Wallabies selectors after being left out of Cheika's squad to play in Japan next month.

Wallabies Tom Banks, Joe Powell, Pete Samu, Rob Valentini and Pulu will use the NRC as an opportunity to stay fit and ready should the Wallabies need an injury replacement during the World Cup.

Banks and Powell have continued to train with the national side as extended squad training members and missed Canberra's season opener at Box Hill.

Banks could earn a last minute call-up after Jordan Petaia suffered a hamstring injury at a training camp in New Caledonia last week.

The teenage sensation has already been ruled out of Saturday's clash with Samoa, but David Pocock is expected to play his first game since March and bolster Australia's forward pack.

The Wallabies will touchdown in Sydney this week to play their final fixture ahead of the World Cup at Parramatta Stadium.

The game will be an important testing ground for Cheika, who will use the contest as the last opportunity to test combinations and players.

Pocock will have his first and last chance to prove his fitness ahead of the World Cup, having been cleared to take part in the tournament after overcoming a rare calf injury.

Christian Lealiifano, Folau Faingaa, Rory Arnold and Tevita Kuridrani round out the Brumbies' contingent.
