Wallaby coach Rod Macqueen is preparing for a torrid battle up front in Saturday's Test against England by naming five forwards on the reserve bench.
In the only change to the run-on side, the hard-running Jim Williams replaces Matt Cockbain, while Waratahs openside flanker Phil Waugh will make his Test debut from the bench.
Waugh replaces injured flyhalf Elton Flatley, leaving just Chris Whitaker and Nathan Grey as reserve cover for the backline.
The selection of Williams ahead of the hard-tackling Cockbain suggests Macqueen has a game plan based around attack, with Waugh adding to the Wallabies' ball-winning options around the field.

Should things become serious in the backline then Toutai Kefu or Williams can fill any holes.
"Jim has been one of our most powerful runners all year, and he could give us some early attacking opportunities," Macqueen said.
"And we've chosen Phil in the squad because we believe he could give us some useful options late in the game."
Just seven players remain from the Wallabies' starting XV from last year's World Cup final.
