In Queensland, like the rest of Australia, we drive on the left hand side of the road. That means that in traffic traveling towards you, in the opposite direction should pass on your drivers, or right hand side.
Drivers from America and Europe will find that the steering wheel is located on the opposite side of the vehicle than they are normally used to. As such, many of the controls, including gear changers, are operated by the other hand than would normally be.
This can take some getting used to and we do not recommend that it is attempted by new or inexperienced drivers. If you are in doubt, or uncomfident about driving this way, then we recommend that you avoid it if at all possible.
