Outspoken Victorian Liberal MP Bernie Finn has posted he is "praying" for abortion to be banned, telling a follower he was not supportive of abortion even in the case of sexual assault.
The comments have once again triggered fury among his party colleagues, with one MP describing him as "an abhorrent human being", while others said he should consider his future.
But the response from Opposition Leader Matthew Guy was much more restrained, with Mr Guy describing the posts as the MP's point of view and not reflective of party policy.
On Facebook, Mr Finn said, "so excited the US is on the verge of a major breakthrough to civilisation. Praying it will come here soon. Killing babies is criminal."
The MP was commenting on a leaked draft opinion from the United States Supreme Court that indicated the Roe v Wade decision, which makes abortion a constitutional right, may be overturned.
Mr Finn has been a long-standing critic of abortion laws and is a regular feature at the March for the Babies rally.
In response to one post that said there should be an option in extreme cases of sexual assault, Mr Finn posted: "Babies should not be killed for the crime of his or her parent."
Liberal MPs are privately disgusted with Mr Finn and are angry his comments are once again distracting from the party's attempts to win office in November.
"The party is so over someone who is so out of touch, he should seriously consider his future,'' another MP said.
"We've got a message to tell Victorians in the lead up to the election, this is not it."
Multiple Liberal sources said they expected Mr Finn to face a preselection challenge for his upper house spot sometime after the federal election.
Others are furious that his comments come during the federal election, especially when the party is facing a revolt from small "l" liberal voters in Kooyong and Goldstein.
Mr Guy said the social media comments were a reflection of Mr Finn's personal views rather than a party agenda.
"That's Bernie's point of view. I am focused on Victoria, not on social policy in the United States," Mr Guy said.
When pressed on the Liberal Party's stance towards abortion, Mr Guy said the historical precedent of conscience voting remained unchanged.
"We've had free votes for many, many years on this matter, they'll always continue," he said.
It is not the first time Mr Finn's social media comments have raised anger and embarrassment for the state opposition.
The party has previously spoken to Mr Finn about false conspiracy theories posted.
Mr Finn has also published memes of Premier Daniel Andrews dressed as Hitler with the ABC logo replacing the swastika on his arm.
Mr Finn has been contacted for comment.
