Things to pack if you're going to Oz:
Most important - a roo riding harness, that's the only form of transport down here, you should probably take some lessons when you get here.
Stubbie holder - you don't wanna make the beer warm now do you? Nobody will take you seriously unless you have one.
Stubbies (short work man shorts) - this makes you a man and instantly gains respect from those who count
A blue sheerers singlet - complements the stubbies well, and gains even more respect from the above mentioned people.
An akubra (aussie wide brimmed hat) with corks hanging from it - keep both the sun and the flies off you
Thongs (not bloody flip-flops) - it's the only footwear down here, if you wear anything else you will be labelled as a tourist and be robbed. Also, when worn in conjunction with the stubbies, sheerers singlet, and akubra you are a man and will be accepted and respected by the locals.
Aussie slang dictionary - you will look like an idiot and a tourist if you don't know common phrases such as 'frog and toad' and 'dead horse'.
Big knife - used for wrestling crocs, killing snakes, fighting roos, and buttering bread. Make sure it is bigger than the bloke's sitting next to you, it gains respect.
A prefered beer - every man knows his beer and drinks only that beer. Without this poeple will think you are unfaithful to women. You will also be robbed.
A liver in decent training - if you can't keep up with the boys you will lose all respect. Doesn't matter if you are wearing the right clothes, speak the right slang, and are a roo wrangler from way back, if you can't drink it's all for nothing.
A stomach that can handle meat pies for beakfast lunch and dinner - it's the only food down here, apart from what you can catch and kill with your bare hands.
A sense of humor - people will take the piss outta you as they do to everyone, if you get offended you will lose respect.
That should get you started mate
