I have lived in Taiwan (mostly Hsinchu, Taipei, and Kaohsiung) for 20 years and in South Africa (Johannesburg) for 12 years. It's now time to move to Sydney and turn over a new leaf in life. =)
There's a lot of things to do. Fortunately, there are a lot of resources on the web that can help, such as the site dedicated to "starting a new life in Australia."
Let's work on each item one by one. First, I'll need to get an appropriate visa so I can work in Sydney and make a living. For my case, it'll be the 457 visa -- Temporary Business (Long Stay) - Standard Business Sponsorship thanks to sponsorship from my current employer. Even with help from dedicated migration agents, there's a lot of documents to prepare (such as resume, transcripts, references, etc.) and I will need to perform health checks with designated panel doctors in my home country after the migration agent lodged the visa application.
