Need to get home for support

I moved from Australia to Canada to be with my now wife, almost 10 years after moving here, 7 of which we have been married, my wife has told me that she wants a divorce with zero chance of reconciliation. Unfortunately it is damn near impossible to live by yourself in canada on the wages I’m on so I think the best thing I can do is head home to Aus to at least be with my family during all of this. I don’t have a specific amount that I know, I just know I need to get back home. Any help would be appreciated. I only have PayPal.

Thank you.
