In Australia's first match of their annual European tour, the Wallabies will take on representative side the Barbarians at Twickenham in London, with former winger Nick Cummins set to line-up for the opposition.

Having lost their past three Tests, Australia will be desperate to turn their form around ahead of four other matches in Europe but they will be reminded on Saturday of the kind of talent they could have at their disposal if they allowed foreign-based players to pull on the green and gold.

Cummins left the Western Force in July to play rugby in Japan in order to provide for his extended family and the 27-year-old is now ineligible for the Wallabies according to Australian Rugby Union (ARU) regulations.

While other countries allow foreign-based players to play, Australia forgoes the talent of the likes of Cummins, Matt Giteau, plus former captains Ben Mowen and George Smith.

Cummins will return to the scene of his first international try at Twickenham and expects a fun atmosphere between the Barbarians and the Australians.

"It'll be great to be back at Twickenham where I got my first (try) and it'll be nice to run out against the boys and I'm sure there'll be some banter and some carry-on," he said.

"The preparation week might be different but what a great experience to be on both sides of the pitch."

The match will also be Michael Cheika's first in charge of Australia after Ewen McKenzie sensationally quit as coach, following the Wallabies' 29-28 loss to New Zealand on October 18.

Australia blew a golden chance to beat the All Blacks, throwing away a 10-point lead in Brisbane.

New Zealand fly-half Colin Slade, who slotted the match-winning conversion at Suncorp Stadium a fortnight ago, will also line-up for the Barbarians alongside compatriots Steven Luatua, Matt Todd and Dominic Bird.

Cheika turned things around at Leinster and the Waratahs to become the first coach to win both a European Cup and Super Rugby title.

While a loss to the Barbarians would ultimately mean nothing in the grand scheme of things, it would make Cheika's job of restoring morale within the Australian set-up a whole lot tougher ahead of Tests against Wales, France, Ireland and England.
