The Adelaide cafe owner is the bookies' favourite for Becky and has impressive odds from both Sportsbet and TAB at 1.28 and 1.12, respectively.
What's more, he has the backing from former Bachelor star Alisha Aitken-Radburn.
"After that photo shoot date and them kissing behind the Akubra, Pete is the winner obviously!" she told Who exclusively.
"I feel like once you’ve been through it and having watched so much, you can really tell when something seems genuine and it’s coming through the screen. There are some times when contestants are kissing and I’m not buying it but her and Pete, they’re in love! I love Becky, I feel like there are more older guys on this season and they seem a bit more serious so I’m liking it."
Pete also has the backing of the viewers at home and has been flooded with supportive messages on Instagram.
"Can absolutely see you and Becky at the end of this journey together," one fan mused.
"I hope you win!!" exclaimed another.
However, some fans suspect that Becky and her chosen guy may not be that rock solid after some very cryptic interview responses.
Whilst her younger sister seems to be head over heels, Becky had a bit more of an awkward answer when hosts Laura Byrne and Brittany Hockley asked if she'd found love on their Life Uncut podcast.
"I wouldn't say love! But I'm definitely in a happy place, so... I feel like the road to love is a bit of a journey right? And I just want that time on the outside to just get to know my person, and have fun and just do real life."
Becky infamously dumped a guy she was casually dating to appear on The Bachelorette with her sister and spilled the details to Kyle and Jackie O ahead of the premiere.
"If I was in a relationship, I definitely wouldn't have gone on the show," Becky said. "I was single, but I was seeing someone for a short period of time there."
The 30-year-old added that she and her fling ended things on "really good terms" and was honest when ending things.
"I said to him, 'There's this opportunity that's come up with Elly for me. It's a TV thing, a dating thing. Just to be clear with you, this is what I want to do.'"
