Hi veronica,
Australia is a great place to live, it has problems but it really is a good life style. They are just about to change the immigration laws, anyone who wants to migrate here has to know about the Aussie culture and must speak and write English. We are multi cultural and the larger cities do have Serbian communities, so you may be able to get that coffee you are after!
The weather is good, and the food is great, we have very strict laws with food and hygiene, you should come down for a visit some time, I am sure you would love it.
