Perform, and a place in the squad for the two Tests against the Wallabies awaits - stutter and it could be an early flight home.

While fly-half Gordon Ross, the only player from Friday's Test side to start again, is vying directly with Dan Parks for a Test start, the rest have a major goal of their own.

Head coach Matt Williams will not finalise which players return to Scotland on Wednesday until after the Waratahs game - and Morton, for one, will bust a gut at Aussie Stadium to ensure he is not amongst them.

The 21-year-old, still adjusting to union following his switch from the Leeds Rhinos, even has half an eye on the lifelong dream of a Test jersey after Chris Paterson's tour was ended by a triple fracture to the cheekbone.

"This is what I have always wanted to do. I have always wanted to play for Scotland and hopefully I'll get a chance to," he said.

"I would be achieving the goal of a lifetime. I moved to England when I was five but my Dad used to always tell his friends that I was going to play for Scotland.

"That has always been my goal. Even when I was playing league it was 'one day, I want to play for Scotland in union' even if it was later in my career.

"First of all it is making the cut, which I would be very proud to do because I have not been in the game a long time. And it has been hard to do, learning a new game, so to make the last 30 out here would be a great achievement in itself.

"I just think I need to play my game against the Waratahs - if I can play the way I like to play then I think I'll do enough but what happens after that is in the selectors hands."
