It's Wallabies scrumhalf Nic White and his national team understudy Tate McDermott. It's flyhalf James O'Connor and rising star Noah Lolesio. It's incumbent Test centres Jordan Petaia and Hunter Paisami and hopefuls Irae Simone and Len Ikitau.

Throw in freakish winger Filipo Daugunu, rugby league convert Suliasi Vunivalu and Test fullback Tom Banks, and Wallabies coach Dave Rennie almost has a selection trial on his hands.

That's without even mentioning the raft of Test veterans and hopefuls in the forward packs, because this is the story of two star-studded back lines going head to head in a clash between Super Rugby AU powerhouses.

The ACT Brumbies will look to continue their unbeaten start to the season when they face the Queensland Reds at Canberra Stadium on Saturday night.

MORE BRUMBIES

But Brumbies fullback Banks says this week marks the club's biggest test with Vunivalu firming for inclusion on the wing in Brad Thorn's starting side, pushing Petaia to outside centre and Paisami into the No. 12 jersey.

It makes for a freakishly-talented back line when you couple those names with the likes of Wallabies trio O'Connor, McDermott and Daugunu.

But standing in their way is a Brumbies outfit boasting Test-capped stars White, Lolesio, Banks, Simone and Wallabies squad member Ikitau.

"The amount of talent they have in their back line is something we're really looking forward to going up against, and it's no different to their forward pack," Banks said.

"We know they're going to come at our set piece and they're really going to lay a platform for their backs to play on. We know we're going to have to muscle up physically and really take it to them.

"This weekend will probably be our biggest test and a big test for myself as well, coming up against a really strong Queensland back line.

"It's going to be an exciting challenge, but one we are really looking forward to. We know it's going to be a big week."
