Fast bowler Doug Bollinger will replace the injured Ben Hilfenhaus in Australia's Test squad for the tour of West Indies.
Hilfenhaus has suffered a recurrence of a stress fracture in his lower back.
"Obviously this is very disappointing for Ben," Cricket Australia (CA) chairman of selectors Andrew Hilditch said in a statement on Tuesday.
"However, given the amount of cricket facing the Australian side in all forms of the game over the next 18 months, a conservative approach to the management of his back injury is best to ensure he makes a full recovery.
"This presents a great opportunity for Doug Bollinger who had a great season for New South Wales until injury ruled him out of the last couple of games of the season."
Left-armer Bollinger, 26, suffered a fractured foot in February but has recovered and will undergo a fitness test before taking his place in the tour party.
Australia play three Tests in West Indies, starting on May 22 in Jamaica.
