What is the weather like across the county?
I am in Brisbane and it can get quite warm during Summer. So very hot for 2 to 3 months of year and perfect for other 9 to 10 months of the year. Funny enough I have just spent 3 months in England and had about 3 weeks max of rain. On return to Brisbane on 1st Jan we have had 4 days of sunshine. Not usual though.
We have aircondioning throughout and an plunge pool in the back yard. tbh only have aircon on a few times in the Summer.
All shops, cinemas, restaurants and such are airconditioned. Most schools aren't though . Our school summer hols are mid Dec to end Jan so only a few weeks of heat for them anyway.
Which places get too hot and which are more like the UK?
Darwin and Cairns would be very hot.
Think you will find most places quite warm until you climatise. Best option would be to arrive March to June so you will have lovely temps for a good six months to adjust. Melbourne and anywhere in Tasmania you will most likeley find "UK" weather. Not as extreme though.
What is the politics like and actual living in Aus? eg. healthcare system, taxes, utilites etc.? Is it always a case of 'the grass is greener' or would living in Aus really be 'nicer' than living in the UK?
Having met and spoken to a lot of families in the UK I think we win hands down. You have the NHS which is free whereas we pay for dentists and doctors. Only kids are usually bulk billed (paid for my Medicare). A standard gp consult would be around $50 = 20 pound and you get half back from medicare if eligible. Public hospitals are free but waiting lists can be long for some things. I pay $160 month for private health = top hospital cover and all of the extras such as dentists, opticians etc.
Not sure about people coming over. Us sahm's are "paid" to stay home with our dc. Depending on what your dh would earn and number of dc you can get up to $500 a fortnight. Couples having a baby get a lump sum of $5000 when the child is born regardless of income.
What is the schooling like? We have 2dc's, our eldest only just started school this year. We would have to move from where we are in the UK anyway for a decent secondary school (our catchment primary school is very good though) so thought if emmigration was a possibility it would be atleast 2-4 years away.
Schools are generally good. You have very good ones and then average ones. I don't think there are any "bad" schools. In Qld you can pretty much choose any school you want your children to go to where you live. You do have to pay for school books and supplies here. My dc's books were around $300 for 2 dc this year. Am in the process of "covering" them with sticky contact. Remember a UK mum her who was shocked at the whole idea of buying books and then covering them as well. lol
What are the house prices like? Is Aus having a housing market boom like we are? Have we missed the boat or are house prices still 'good' over there compared to in the UK?
In my neighbourhood (35 mins from Brisbane CBD) a brand new 4 bed, 2 bath, 3 living room house on 800 sqm will cost you $440,000 to $500,000 (less than 200,000 pounds). Council rates (tax) are approx $1800 a year.
Renting a house same as above would be around $350 a week.
I guess you have to see for yourself. We have a large number of expats in our area who love it. I have become quite close with an english lady and an irish lady in particular. They desperately miss their families but claim that the lifestyle for their dc outweighs that. Their dc do outdoor sport and activities all year round after school. You can swim for 9 months of the year.
I also have a lovely english friend who came over in 2004 with her dh and dd. She hated it. She stayed two years and went back with her dd. Her dh stayed here . She is english through and through and could not adjust. She missed her family too much. I visited her when I was in the UK in December and she is much happier back where she belongs.
