Wow... is this thread still active!?

Depends on your profession, to be honest. Australia is also in a midst of a economic downturn.

There are essentially 2 groups of migrants - broadly speaking.

The first are those awash with funds and are looking to migrate from a position of strength, on their terms, when they feel is best for themselves. A job is secondary. They are looking for things that their country of origin cannot provide: perhaps it's the weather, a different pace of life, the education system for their kids, the lifestyle. This group are immune to the economic cycles affecting their chosen country of arrival. As long as a visa is obtained, they'll go regardless whether there's a job waiting for them or not.

The second group are those that the "/ktard know-it-all-although-they've-never-done-it-themselves" expert would call the Bangla migrant. Those who are going there to compete with the host country's population for what these keyboard warrior so-called experts term a shrinking economic pie. You'll see many such comments whenever a question arises about migrating/moving to Singapore (why would you want to work there? You'll end up like sardines in the MRT and living in pigeon coops, and you'll be a Bangla), or Australia (why would you want to move there? It's so racist and you'll face hurdles getting a job because you don't look Angmo, and you'll end up a Bangla). The only common themes are: (1) these self-proclaimed experts have never done it before themselves - and it's often anecdotes heard from a friend of a friend's neighbour's daughter's tuition teacher, and (2) this weird fascination about Banglas.

Anyway, if you belong to this second group of economic migrants, then, it stands to reason that you do your sums more carefully before you pull the trigger. Compare what you're making and the cost of living, as well as your career progression and your financial returns in your home country, and then contrast that with the expected parameters in your target country. To do that, there are websites that list the median salaries of occupations in Australia (google's your best friend) - but bear in mind this: (a) it may not be possible to get a job that equates your last position (b) different cities have different cost of living (and you can find out more about that with Numbeo, from the web) and ( c) the taxes are going to be different and will need to be factored in.

Good luck!
