I thought I was able to understand any English accent in the world, since I work with Americans, Indians, Chinese and off course, Brazilians.  Poor guy It was until I started having to argue with Australians.
The Australian accent is so different in a variety of aspects: fresh new slang, completely different pronunciation,  an intonation which makes their sentences sound like questions, vocabulary, etc.

I realized it would be prudent if I had some training on this new stuff, before arriving there.

So, there is it. These are the resources which are helping me to enhance my Australian Communication Skills.

Accent

Although listening to radios is not the best way to learn their accent, due to the very clear English the radio professionals speak, it is still an alternative. Specially because you some of them allow you to download their Podcasts and listen everywhere.
Follow my preferred radios:

The Angy Aussie. Not that I really enjoy all that  he says, but it  is a really rich source of vocabulary and the channel is updated very often.
