It all depends on your bachelor degree background, your area of interest and your work experience.
To be eligible for a Masters course in Australia, you will need to have the degree that deemed as equivalent to Australian Bachelor Degree. You will need to fill in the application form and send them together with the certified copy of all of your academic transcripts. If they cannot accept you for the Masters course, they may offer you a place in their Bachelor degree course with credit transfer, so you do not have to study from year 1 again.
There are only 42 (soon to be 43) universities in Australia, all of them are fully accredited and they are tightly controlled, 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.
To find out the latest info abt course that you are interested in taking and where it is offered, I suggest you to go to the Dept. of Education, Science and Training website ((http://cricos.dest.gov.au)
or IDP Education Australia (www.idp.edu.au). It will give the list of institutions that are able to offer courses to international students who wants to continue their study in Australia. The info abt fees and requirements are available from the universities' websites. Please make sure that the information you are accessing are the one for International Students.
Now... some ppl may suggest MBA course, but it may not be a suitable course for you. First of all, if you have just completed your bachelor degree, most MBA course requires minimum of 2 years work experience in managerial level.
Second, if you have done a business course. MBA is actually created for ppl who do not have business background (eg, Engineer or Lawyers) but already got the work experience in managerial level. MBA course basically a fast-track business course where the students got the business course for abt 1-1.5yrs that usually given to undergraduate students for 3 yrs. MBA course is also a place where those managers exchanges ideas and experiences in real-life case studies. Therefore students who do not have work experiences before sometimes feel singled-out.
If you have business background, you might consider a specialisation course, eg. Master in Accounting/Marketing. So this is to 'deepen' your knowledge.
Hospitality industry is also the area where lots of demands in Australia.
At the end of the day, you will need to take the course that you really interested in. There's no point of us telling you what's good in the market if you dun have any interests in that area so you will get good grades in your transcript.
After you have got your masters and applying for work, the employers will want to know if you have got any work experience before getting your master, since for masters graduates, what you are applying will be in jobs in managerial levels, with manager's salary. So it is obvious that if you got masters degree and no work experience, you'll be in trouble.
Hope this helps. Good luck on your study and welcome to Australia.
