Joe Launchbury will make his first Rugby World Cup start in England's make-or-break clash with Australia tomorrow.

The former Worthing Raider has come off the bench in England's first two group games but replaces the injured Courtney Lawes at lock in a game England must win if they are to progress to the knockout stages.

Launchbury joins fellow Sussex star Joe Marler in the pack for the showdown at Twickenham as England bid to bounce back from their defeat to Wales last week.

Coach Stuart Lancaster makes two further chances with Jonathan Joseph returning from injury at outside centre in place of Sam Burgess while Ben Morgan takes over from the injured Billy Vunipola at No.8.

England: M Brown; (Harlequins), A Watson (Bath), J Joseph (Bath), B Barritt (Saracens), J May (Gloucester); O Farrell (Saracens), B Youngs (Leicester); J Marler (Harlequins), T Youngs (Leicester), D Cole (Leicester), J Launchbury (Wasps), G Parling (Exeter), T Wood (Northampton), C Robshaw (Harlequins, capt), B Morgan (Gloucester).

Replacements: R Webber (Bath), M Vunipola (Saracens), K Brookes (Northampton), G Kruis (Saracens), N Easter (Harlequins), R Wigglesworth (Saracens), G Ford (Bath), S Burgess (Bath).
