I don't blame you @GreenestGrass ... Whilst I'm sure Australia is a lovely place with fab weather, you couldn't pay me to live there/move there. And I don't actually understand why people elect to move there tbh.
I never understand why people want to go, because as YOU say, it's soooo far away from the rest of the world, it takes DAYS to travel anywhere, everything is so expensive, it's so hot, and there aren't that many opportunities. Plus, all the flies and snakes and huge spiders etc... No thanks.
No offence sorry, and I know this is your country, but I really wouldn't want to live there, and I do LOL at people who say 'I went for 6 weeks on holiday, or 2-3 months backpacking and was super happy there, so I wanna LIVE there,' because they are DELUDED if they think living there will be the same as a 'holiday.'
Also you can say goodbye to any family or friends, because any relationship you had will very likely be gone. I have known a few people who moved there in the past, and they saw their family once or twice in about 8 to 10 years. Wouldn't be for me. No way.
This reminds me, I knew a girl at school who emigrated there with her family when she was around 14 (late 1970s.) Her dad was a minister and got a placement over there. I found her on Friends Reunited some 25-26 years later, and we messaged each other back and forth for a few weeks.
She had stayed in Australia, (all the family did actually, mum, dad, and brother who was 6 at the time.) She was married to an Australian man and had 3 sons.
I was both amused and slightly annoyed when she emailed me and said 'I am sending some photos of my house, and garden, and swimming pool to make you jealous.' I thought 'cheeky cow
I am not jealous of anything. I have a lovely home, a lovely garden, and I live in a lovely country.' I did not respond.
She emailed AGAIN a few days later, saying 'I am enclosing some more pics to make you jealous again
The beautiful sunset over the sea on this lovely hot day while you sit in rainy England.'
Because the sun never sets over the sea here, and the sun never shines, and it rains 24/7! 
I just messaged back and said 'nice pics, I hope your week is going well.' She emailed back, and said what do you think of our pool? Are you jealous you don't have one in your garden?' 
Utterly bizarre.
As I said, she had 3 sons... I emailed her a picture of my DAUGHTER and said 'here's a photo of my daughter. Are you jealous you don't have a daughter?' 
Never heard from her again.
