The Aussies are coming and there's going to be fireworks.

That's the view of Bulls star Iestyn Harris ahead of the club's Carnegie World Club Challenge duel with Wests Tigers.

Hitting back at rumours the Australian premiers are taking the up-and-coming clash lightly, the stand off believes exactly the opposite.

"It's been a little bit inconsistent over the last thee or four years with some of the sides the Aussies have brought over," he admitted, prior to the February 3 tussle.

"But now I think Australia - certainly with the obvious success of the Tri Nations - are giving British rugby league more respect.

"I feel their clubs are now starting to take the World Club Challenge seriously," said Harris.

And Harris is adamant the game is building up to be a cracker with both camps seeking victory for different reasons - the Bulls to become the only side to lift the trophy three times and their opponents to mark their arrival on the world stage.

"Wests Tigers have not had great success over the years and the Grand Final last season is the first major trophy they have ever won," continued the Great Britain ace.

"To be crowned World Club Challenge champions will be a big feather in their cap so we have two sides desperate to win.

"That always makes for fireworks and I reckon that's what the crowd will get at Huddersfield.

"They've got some brilliant players and we're all now eagerly anticipating it after the practice we've done over this last week."

The Bulls have been preparing for the clash in Lanzarote but return to England tomorrow.

Meanwhile, prop Anthony Tonks, 20, has joined Doncaster Lakers on a year-long loan.
