ALN78 said..Thanks guys, this is all very useful. Heading up tomorrow morning- yes …even got the drill!!

please drive safe.
better to cruise and take your time, and arrive a little later, then to copy some of the more reckless drivers out there who maybe (or maybe not in some instances) have alot more experience on our country roads.
give yourself plenty of time if overtaking, watch out for roos and other wildlife (including cows near shark bay!) especially at dawn and dusk, and stick to the speed limits when you go through the towns, even if it seems like there is no one around...
and then have fun on the water!
enjoy
