As for big sister Becky, 30, she's been tipped to pick 34-year-old Pete Mann at the end of the series.
The Adelaide cafe owner has impressive odds from both Sportsbet and TAB at 1.35 and 1.15, respectively.
And after the steamy outback themed photo shoot, sparks were certainly flying between the pair.
The couple even shared a steamy kiss behind a hat leaving Becky "lost for words."
One thing we can guarantee is that Elly and Becky will never go for the same guy.
Though they're into someone with the same values, the Miles girls have made a pact to say no to conflict.
“Our main thing coming into this as we were in discussions was we didn’t want there to be any kind of drama between us,” Elly, 26, told The Daily Telegraph.
“We knew there wouldn’t have been any drama on our end but we wanted to make sure that was across the board, that we would have a wholesome story unfold and no bull***. We were reassured that they wanted us to find love.”
“There were a few times where maybe both of us thought someone was cute,” Becky previously told New Idea.
“But then one of us would be like, ‘I want to pursue something.’ So when Elly would say that to me, I was like, ‘Yeah go get it, girl!’”
Elly added that she’s never taken a liking to anyone her sister has dated.
“I just automatically put them in the ‘brother basket’ because that’s what they’d be to me. I’d never be like, ‘Oh, I’m going to see if I can get in myself,’” Elly added.
