Thank you, It's really helpful to know that I'm at no disadvantage by being in Australia, although if I did plan on being employed in this particular region of science would this mean I would almost certainly have to move permanently move to another country such as America for example? Also would you happen to be able to explain in depth, the amount of work and difficulty that goes with studying cosmology?
I think anyone in academia should be prepared to move temporarily or permanently to wherever the job is, if they want a career. If the job is in the US, then sure. You should know that there aren't very many cosmologists in the world. Estimates of the number of all astronomers in the world hovers around 10000, I don't know how many cosmologists there are, but far fewer than 1000, I'd guess. That's not a lot of people.
Also, here's a list of the astro departments in the country. You should aim to do undergrad at one of the universities mentioned here. Personally, I traveled across the country for undergrad, partly because of the reputation of my undergrad institution for astro.

I can't explain in depth the work and difficulty into becoming a cosmologist, because I'm not one! I was heading that way until 3rd year of undergrad, before I realized that
doing cosmology/astro is far different from
studying cosmology/astro, and I was much more interested in
doing physics.
But, here's a quick run down of a typical plan in Australia: Get a good university entrance score (whatever the acronym is for your state), get into a good BSc program, major in physics and astrophysics, if there is a astro major, or physics and something else relevant (mathematics, computational science, theoretical physics, double physics major, chemistry ... something). During undergrad, do research projects in physics/cosmology/astronomy. If the university doesn't offer undergrad research in these fields, go elsewhere (most do.). Do a diverse range of projects. This is where you will find out whether or not you like research at all. Do some summer internships. Places like CSIRO and AAO and many universities offer them. Get into honours. Do honours in astrophysics or cosmology (or physics or mathematics, it doesn't matter awfully much, but doing one in astro/cosmo is better). Get first class honours, so you can get a PhD scholarship (APA). Apply for a PhD with a cosmologist, and do a cosmology PhD!
ETA: Look at this!
