It takes time and much effort for you to apply for an Australian visa. You can ask for the Australian embassies for the instruction and help. For example, if you are in Canada, you should visit Australian Embassy in Ottawa or Australian Embassy in Canada. The interview or character examinations are all in the office of embassy. The officer will help you much during the procedure. Visit the site http://www.embassy-info.com/australian-embassy-in-ottawa-canada.html for more information about Australian Embassy in Canada.
