I enjoyed the glasshouse mountains when I was round that way, Canada has some awesome mountains. But if your into that kinda thing (like I am) its pretty cool. The Steve Irwin crocodile farm is on the way if I remember right. There's a go cart racing place which is fun & that pub from the cartoon, forget whats its called. But just laugh at it as you drive past, don't go in, its overpriced...You can grab some fresh strawberries along the same road most of this stuff is on as well.
Heaps for him to do really if you don't mind going for a bit of a cruisy drive. I recommend the trip advisor phone app, has heaps of ideas & info for places when they go there...but we passed through there about 7 years ago & just got all the info from tourist brochures
