CANBERRA, Australia - A senator has introduced a bill that would legalize same-sex marriage in Australia and allow only churches and ministers of religion to boycott such weddings.

A voter survey released Wednesday showed Australians support legalizing marriage equality, and the government had promised if that was the result, Parliament would consider a bill in its final session of the year.

The bill introduced Wednesday is favoured by Prime Minister Malcolm Turnbull, who urged lawmakers to heed the survey results.

Debate has been intensifying over the possibility of gay wedding boycotts and refusals to provide wedding venues and other services. A draft gay-marriage bill released Monday by other government lawmakers has been criticized as lessening protections for gays against discrimination.
