The couple recently split amid allegations that he had an affair with 26-year-old dancer Francine Cornell.
Despite finding a new bachelor pad and buying a new TV, people are speculating that Yvonne may be about to take Boyzone singer Ronan back.
Yvonne has joined the family in Australia, and was spotted playing with her kids in a theme park.
A source said: “Yvonne is here but of course no one wants to intrude and ask them what’s going on.”
She wasn’t wearing her wedding ring, but some think her presence alone may suggest that the couple are trying to patch things up.
