If you are coming out to ride a couple of things to remember... watch out for the local wildlife on the roads!!! early morning and dusk are the most dangerous times for this... ( Kangaroo's, Koala's, Wombats may look cute and cuddly but are NO fun to hit with any type vehicle!!! )
And we drive on the Left side of the road!!!
Hope this helps!
