MOST gay Australians do not support a plebiscite on marriage equality.
A survey by Parents and Friends of Lesbians and Gays of 5500 gay men, lesbians, bisexuals and transgender and intersex people shows 85% want the Federal Government to put the issue to Parliament instead of rolling out a public vote.
PFLAG national spokeswoman Shelley Argent said when respondents were asked what advocacy groups should focus on, 78.3% wanted them to "work for a successful vote in parliament".
"The missing voice in the plebiscite debate has been the LGBTIQ community," Ms Argent said.
"Now they have spoken and emphatically said no to a plebiscite under any circumstances."
Prime Minister Malcolm Turnbull has indicated the poll may not happen until next year.
PricewaterhouseCoopers believes the poll would cost more than $525 million.
