Astrophysicist Matt Agnew is reportedly the first suitor on The Bachelor Australia to take things to the next level with a contestant on the program.

According to reports on New Idea, Agnew slept with one of the women during filming.

"We're told the astrophysicist even beds one of them and it's not the woman he ends up picking at the final rose ceremony," a source told the publication.

If this proves to be true, Agnew would be the first suitor to become intimate with a contestant during production.

Previous bachelors on the program typically wait until after the finale has wrapped up before they consummate the relationship.

Network 10 personality Grant Denyer revealed on the 2Day FM breakfast show in August last year that sex was off limits for those participating on The Bachelor.

"You're not allowed to get it on. There's no sex allowed on set," Denyer said.

The former Family Feud host revealed that the rules are slightly different on Bachelor in Paradise.

"You have to announce to the whole crew that you're about to do it and they go, 'bring in the consent camera'," he said.

"And they bring in a consent camera where you go to confess to everybody on production that 'I consent to doing this,' before you actually do it in front of everyone. That is the formal process of how to get it on, on television in Australia for 2018."
