Will I find a job in Australia?
YES!
You WILL find a job in Australia if you really want to work here (provided you have a visa that allows you to work legally).
Australian Job market
Australia is a huge nation with a major economy (The Australian dollar is the fifth most traded currency in the world) and there's only 20 million people living here (try comparing that to the 300 million who form the US economy or the 128 million constituting the Japanese economy!)
Personal experience with finding a job in Australia
I personally found a job in my own field (web designing) in less than 3 months after I arrived to Australia and I know many who have done the same, however if you feel you can't wait you can always opt for a temporary job just to get some income going on, something like working in a deli or restaurant or gas station (by the way you only work behind a counter in gas stations, here the customer fills up his/her own gas tank then comes inside to pay). A good place to start looking for these jobs are the local newspapers and if you manage to contact others from your same nationality before you land to help you look for a job.
Temporary jobs in Australia
Pay in temporary places obviously won't make you rich but it will cover your necessary expenses... and don't feel that it's a shame to work in such places that are culturally inferior in your old country, remember always that people here think differently and good luck!
