G'day,
I can only help with the Australian university question.
Some may argue that the Australian universities belong to The Group of 8 (
www.go8.edu.au) are the 'famous' one. University of Western Australia (UWA) is one of its member. However the group was formed just to unify the promotional effort. The members cannot claim that they are the best at everything that they offers.
There are only 42 (soon to be 43) universities in Australia, all of them are fully accredited and they are tightly regulated, therefore the quality and recognition of their graduates are equal from wherever university you are studying from. The most important thing is you have to READ the course information carefully, since some courses may have the same name but different content.
I suggest you to go to the online database below. It can show you which universities offer the area of study and their website. Once visited the website, please make sure that you access the information for international students, since some requirements, application form and fees are different than Australians'.
Once decided on the uni, fill in the application form and send it together with certified copy of your academic qualification. Depending on your country of origin, you may also need to submit an IELTS test results for proof of your English proficiency (
www.ielts.org)
Living cost... Sydney and Canberra have the highest living cost, followed by Melbourne & Brisbane, then Perth, Darwin, Adelaide & Tasmania the lowest. .
So with many options for your to choose, this is my suggestion to narrow down your choice:
1. Choose the city you want to study in. The consideration maybe the lifestyle, living cost and weather.
2. Find the area that you want to work/career in. Check if the uni's are offering the area.
Hope this helps. Good luck for your study and welcome to Australia
