How to Learn English in Australia

I'm thinking so I could put together over a period of time 100 or so lessons with dialogues, with explanations for pronunciation for words. And then the second thing is I'm thinking about putting together that kind of guidebook slash Aussie English resource for sale on the website. That's probably enough for now but I would really love for you guys to let me know what you think. If you've any suggestions, please feel free to send me any kind of criticism,. good, bad, as long as it's constructive and I can use it to improve what I'm doing.
