I am no angel when it comes to driving and I am probably as inconsiderate as the next person, but when we went to Brisbane in April, I noticed that the driving habits were unlike anything you might experience here. I think here in the UK we specialise in road rage and speeding. In Queensland, it is something else... Lane indiscipline features high on the list, I noticed that overtaking on the inside is the norm, and the tighter the gap the greater the challenge!! Also filtering traffic...should read " I don't fancy your chances mate"
Maybe it was the Easter holidays with lots of tourists around or is there a problem in road etiquette? We noticed that the road toll is very high in Qld which leads us to believe a large 4x4 might be essential.
Any thoughts?

yea i live in brisbane mate was a tame slow driver when i came out here you will fit rite in just drive it like you have stolen it thats the way so they say if you cant beat em join em

You are allowed to 'undertake' in Vic and I would imagine it is the same in QLD. The only exception is where there is 2 lanes of traffic but no painted lines seperating the lanes (if this makes sense.)

Reading the local road rules is a great idea as you will find differences!

Driving is shocking here in Perth to - I think road manners were left indoors - I've not seen anyone acknowledge a thank for letting them out of junction, passing in front, swopping lanes if traffic stuck etc etc.

So now like the other said, if you can't beat them join them!!
