I think the problem is not about finding resources but about culture of the country and their work culture
I'm French, long time ago as long as I was looking from France to work in the UK, about 9 out of 10 recruiters ignored me.
Once I landed in London and did the same search of jobs, interviews piled on me.
I'm not saying you can not find anything from remote and online, just saying it seems much much easier to find something once you are already in the country.
Similar thing happened to me with a much shorter move: central NJ to Philadelphia suburbs. Once I started using an address local to my job search I had no issues getting interviews. Before that was rough and the distance was only 100 miles.
