Camilleri, who was the 16th seed in Canberra, suffered the injury at the Malaysian Open two weeks ago.
She pulled out of the Singapore Masters the following week in the hope she would recover in time for the Australian Open, however, she has since discovered the injury is worse than she first thought.
Camilleri’s injury has meant good news for Hobart’s Maggy Marshall, who comes into the main draw as a replacement, avoiding the tricky qualifying tournament.
Marshall will take on eighth seeded New Zealander Joelle King and said she was thrilled to make the first round after falling in qualifying in 2010.
“It gives me great peace of mind to go straight through to the main draw,” Marshall said.
“It will be hard taking on Joelle, because she’s been going really well lately, so it will probably be more about gaining experience.”
Switzerland’s Gaby Huber has been elevated to 16th seed and will now play Melbourne’s Sarah Cardwell in the first round.
