Is it tough to get a work visa in Australia after graduation?

[Sana Shaikh]

And for how long can I stay back?

Most probably, if you have a degree from an Australian university you will be eligible for a post-study work visa.
For that...
What I would recommend is for you to start creating a strategy to achieve your goals

1. Research your industry in Australia.
   Research what companies are looking for in an ideal candidate.
2. And then start gaining experience in the Australian market as soon as possible.
   Internships and part-time jobs in your industry are an excellent idea.
