The state's peak medical body is among a chorus of stakeholders lobbying the government to make an informed choice on a new alcohol warning labelling system.
On Friday Mental Health and Wellbeing Minister Jeremy Rockliff will vote on a decision between labels, at the Australia and New Zealand Ministerial Forum on Food Regulation.
The Australian Medical Association is among more than 150 organisations and 3500 community leaders and advocates across Australia who have signed an open letter sent to forum ministers.
Friday's vote is aimed at preventing harm caused by prenatal alcohol exposure, including miscarriage, stillbirth and Fetal Alcohol Spectrum Disorder.

AMA Tasmania spokeswoman Dr Jennifer English said the evidence of women drinking during pregnancy was reflected in Australia's rates of FASD.
"It is a devastating, but an entirely preventable disease which causes neurological disturbance," she said.
"Alcohol crosses the placenta and damages the developing organs. It results in intellectual disability, mental illnesses and has a devastating effect on communities. The information about what's safe during pregnancy is conflicting, but the data is clear that there is no safe amount of alcohol."
Consumer testing conducted for the Foundation for Alcohol Research and Education compared the effectiveness of five different warnings, building on evidence-based work by Food Standards Australia New Zealand.
Dr English said a red, white and black pregnancy health warning label had been proven to be the most effective option.
"The research and the investigations the AMA has done shows this small change could have a huge impact on the quality of life," she said.
"The transparent backgrounds just don't get the message across, and that's dangerous for women and communities."
