One of Brisbane's leading priests says it's time for Australia's politicians to "step up to the plate" and do their jobs by legislating for marriage equality.

St John's Anglican Cathedral Dean Dr Peter Catt will on Saturday address a marriage equality rally, where he'll be one of several speakers calling for the federal government to hold a free vote for gay marriage.

Noting he encounters some opposition from conservatives within his church, but also much more support, Dr Catt said it made no sense to withhold marriage from same-sex couples.

"This is the next evolution," he said. "Marriage has become more and more of a celebration and a commitment of the love between two people."

"I think society is more than ready for that expression of marriage and the polls back that up."

Advocating for marriage equality for the past 30 years, Dr Catt said MPs need to take note of surveys which show 72 per cent of Australians wanted to see same- sex marriage legalised.

"The time is here and all we need is for the politicians to step up to the plate and do what they are there to do," he said.

"They don't have plebiscites to send young men to war."

Dr Catt is one of the several speakers at the GetUp! and Equal Love Brisbane event at Queens Gardens in the CBD at noon on Saturday.

GetUp! campaign director Sally Rugg said the rally was being held amid rumours moderate Liberal MPs were preparing to trigger a partyroom debate on the issue when parliament resumed next month.

"There are a lot of MPs and senators in Queensland who are still undecided on marriage equality," she said.

"We're trying to show that this isn't an issue that's going away."
