The Penrith flyer has been named on an extended bench for the Elland Road match-up following his debut hat-trick against France last Sunday, with the final make-up of the team to be determined by whether or not the game will be affected by rain.

Australia's lack of an X factor off the bench was exposed in the 20-20 draw with New Zealand in their tournament opener.

''Jennings is still in the mix he's a match-winner,'' Sheens said.

''I'm just playing that one close to my chest.

''I've told him to keep his shorts ready, that he's not just part of a squad.

''My main worry is will it be wet or will it be dry ... there's the referee there's lots of things to consider before we finalise things.''

''If it's wet and England go with the four big blokes we may have to go with some size.''

A wet night seems to be England's best chance of causing an upset, having used the heavy conditions at Huddersfield last weekend to its advantage as it rumbled over New Zealand with its monster forward pack.

England coach Tony Smith is likely to go with a similar set-up against Australia with four props in the starting side and Sheens may be moved to counter that with some size of his own.

He has plenty of options to choose from, having named four forwards David Shillington, Brett White, Anthony Watmough and Sam Thaiday along with Jennings and utility Kurt Gidley on a six-man bench.

Watmough's relegation comes as a result of Luke Lewis's surprise inclusion in the starting line-up, with Lewis's strong form throughout the tournament and ball-playing skills helping him get the nod.

''I like Luke's ability and his size and his speed and he makes really good decisions in defence,'' Sheens said.

''The fact that he's played halfback and he's played second row and centre that just shows you that he is a footballer, and I like football players.
