Queensland's Lachlan Stanford will step up to join the Senior ISDE Squad, following Price's withdrawal from the event.
Stanford was originally named as a reserve for the team, but has been asked to compete for Australia after Toby Price pulled out of the event due to rally commitments.
Lachlan Stanford represented Australia as part of the Junior Trophy Team last year, where he finished 22nd outright and eighth in the E3 class. The Junior Trophy team took out third place at the 2014 ISDE.
The 2015 ISDE will take place in Kosice, Slovakia from 7-12 September.
