Postdocs, research fellowships and academic positions

[DisplayNameRequired]

I recently obtained my Masters in Applied Linguistics at an Australian university and am currently considering applying to complete PhD (also in Australia). I love the field, enjoy doing research, and my minor thesis and coursework were extremely well-received. My main concern at the moment is whether I'd get any kind of work at the end of it all, and whether the work I'd get would allow me to avoid, e.g., sleeping on park benches and eating out of garbage bins. 

I've talked to a number of people about this and am trying to get as many perspectives as possible. I'd be applying for jobs globally at the end of the PhD so I'm interested in finding out how this works in other countries especially. I'd be appreciative if anyone who knows a bit about the field could give me some advice - I was wondering specifically: 

1. How well-paid are postdocs in Applied Linguistics? How many years would you usually spend at this level in order to stand some chance of getting either a research fellowship or an academic job? What kinds of things (e.g. what kind of publication record) do you need to be considered for a postdoc? 

2. How well-paid are research fellowships (in your country)? What do you need to do in order to get one? 

3. What is the likelihood of getting an ongoing academic position in Applied Linguistics (i.e. not casual)? Is it practicable to get one without having worked casually first?

4. I've met a couple of people who have obtained an ongoing academic position pretty much straight after PhD, however it was some time ago. Is this even possible any more? How often does it happen? What kinds of things would universities look for (e.g. publication record, teaching experience, etc) in order to consider this? 

5. If academic jobs don't work out, is there any advantage to having a PhD in Applied Linguistics in terms of getting jobs in industry? Without going into detail, the area I want to research is pretty heavily SLA-oriented (so, e.g., it has nothing to do with computers or anything else there's any obvious demand for, at least that I can think of). 

Thanks for any help you can give me.
