MPs against marriage equality are reportedly planning to delay and derail the bill that could follow a Yes win in the national postal survey.

Conservative politicians are plotting to attach over 100 amendments to destabilise the progress of marriage equality, according to Pink News.

Anti–marriage equality MPs will not concede in the case of a Yes win.

While the survey is non-binding, the government has said that if it shows the majority of voters support marriage equality, the matter will progress to parliament.

The marriage equality bill is likely to be similar to that proposed by Liberal Senator Dean Smith, which is modelled on the marriage equality laws of other countries including New Zealand and the UK.

Senator Eric Abetz, known for his anti-LGBTI politics, said he would support amendments seeking ‘freedom to discriminate’ loopholes that activists say would undermine LGBTI rights.

“[The bill] is seriously inadequate, as parents, freedom of speech and religious freedom, along with conscientious objection, all need full protection,” said Abetz.

Sources say the group of conservative MPs could smother marriage equality legislation with amendments, delaying resolution of the issue.

Smith said parliament should not allow the bill to be passed if it is attached to amendments undermining discrimination protections.

“If there is a Yes vote, it will be necessary for the opponents of marriage to detail their amendments,” said Smith.

“This will provide a challenge to the Liberal Party because the community will not accept any winding back of Australia’s well-established anti-discrimination laws.”

Experts are now saying marriage equality by the end of the year, as previously suggested by Prime Minister Malcolm Turnbull, is unlikely.
