The actor - part of the Summer Bay soap since 2007 - revealed that the plot will begin later this year.
Miles's last love interest was John Palmer's daughter Shandi Ayres (Samantha Tolj), but their relationship proved short-lived.
Asked by Holy Soap whether Miles could find love again, Quong Tart replied: "You know what? It's coming. He finds someone. I don't know how long it lasts - it could be another Shandi and last a couple of weeks - but he's more surprised than anyone that it happens."
On whether the relationship could be with an existing Bay resident, he continued: "It may be. I found it very intriguing. When I found out, I said, 'Oh my God! Okay, sure. Let's do this'.
"This particular person I'm working with I really enjoy working with as an actor. There's a real ease to what happens when we act that I really enjoy."
