We have cattle ticks and lots of other different varieties of ticks, and yep, they'll suck on a roo too if they get a chance. Roos are pretty diligent with their grooming though, so they don't usually last as long as they do on cows.
We also have great big slimey leeches, one of which decided to make a meal of the soft flesh between my big toe and second toe a couple of weeks ago. I flicked it onto the road after pulling off the highway when I discovered it, and my oldest son was worried I'd run over it. I certainly didn't care.
