Where's wally?

In our garden, that's where. A little pandemelon (a type of small wallaby) has taken up residence in our garden. Pretty surprising seeing as we live in suburbia 15 mins from downtown Hobart. He's spent all day hiding under a bush, only disturbed a few times by Smoke, Tasha and us as we didn't know he was there. Now we don't know how to get him to leave. Smoke has tried chasing him out of the garden (which isn't fully fenced), but he just returns. Any experts on wallaby behaviour do get in touch..
