Brisbane people - Im keen for a coffee.
Kids see the school dentist at primary school. A big van goes to every school and the kids get free dental treatment. You can get free dental care - basic and nothing fancy - at the dental schools and some hospitals.
Get private health insurance. Is nothing like UK health insurance. It is much better. MBF and Medibank are the big ones.
The snakes and spiders will not lurk in every corner waiting to get you. The things that will get you are green ants (check the grass before sitting down) which bite and the mozzies. Oh and bindii's, which are prickles that grow in the grass in summer.
You can drive at night in the bush. Just remember that if you are speeding and swerve you will die and the kangaroo will survive as you skidded off the road and hit a tree. But then again if you hit a roo at high speed and it comes through the windscreen you will die as it will kick the shit out of you as it dies. So miss it if you can safely.
Buy fruit and veg from the local markets. They are held at schools and town halls etc. Just look in your local free magazine/newspaper that every town has.
You will get a load of junk mail (free brochures from the stores). Put a no junk mail sign on your letter box if you dont want it as you get heaps of it.
And yes magpies are territorial and will dive bomb you as you walk under their nests. If they come for you put your head down, wave your arms around your head like a loon and run. They attack everyone and people will yell if they see one coming. Luckily they only nest in spring and the councils remove the evil ones. We used to wear ice cream containers on our heads at school when we were outside.
One thing I did when I moved back in January was go to poundland and buy a heap of toiletries which I shipped over. Is saving mea fortune. Also makeup. Vitalumiere at boots is £31 here is is $100.
