Overall I loved it, but Brisbane was my least favourite area. Melbourne was my favourite followed by Sydney. Personally the thing's I disliked about Aus outweighed the things I liked, so I didn't stay longer.
It's definitely worth considering, I had friends that stayed there, had their kids there & came back 8 years later.
I spent a month putting up pallet racking in Brisbane. Enjoyed the job but it was by far the grimmest place I went to in Australia! Like Chesterfield but a bit more soulless.
Given your history of injuries and the vast amount of dangerous wildlife in australia I'd recommend investing in a stout suit of armour to keep you alive if you're gonna head that way paul.
Queensland is objectively more dangerous than other areas of Aus in terms of crocs, snakes, sharks and jellyfish if thats relevant. I also recall that beach scene isn't as good as you'd think around Brisbane due to the box jellyfish which renders a lot of beaches dangerous for a good chunk of the year.
And it is very hot for a lot of the year, I mean really hot, and humid.
In terms of Aus more generally it’s an amazing place but after I'd spent a year there the relentless racism had become too much for me to bear. Queensland does not have a good rep in this regard. However, the climate is obviously awesome and the standard of living very good for the middle classes.
I found earnings hard to quantify in conversations with friends and family there. On paper salaries are good, and housing appears better value...
II loved the Blue Mountains and could still be there if my girlfriend of the time hadn’t been set on moving to the red centre (she now, of course, lives in Katoomba!). Australian landscape is spectacular but harsh, as well as family and friends I most missed green rolling hills. I'm also pretty snobby in my music tastes and Australia couldn't give me what I wanted in that respect.
Please bare in mind my experience of Brizzie/ Aus is from 13 years ago.
