The Australian Medical Association has warned against getting the flu jab too early this year, with some pharmacies already offering the shot.
Given the horrific flu season last season, some large pharmacy chains are offering the shot to combat the outbreak.
However, according to the AMA's national president Michael Gannon, the timing of the flu shot is critically important.
"We are concerned when pharmacies are out there advertising early flu shots at a time that might not be clinically appropriate," he said.
"Doctors are working closely with the Health Department in Canberra on this year's seasonal vaccination program, trying to get the best possible value out of the huge investment and to protect as many vulnerable populations as possible.
"Remember why you need to have a vaccine every year is the influenza virus rapidly and quickly mutates. It will be appropriate for some patients to defer having their flu shot until well into April."
