wow...the leighton carnival...no, can't say I did miss it.
I find the general cost of living cheaper, I spend no more than $150 on shopping a week, but that is just for 3 of us. It's around 70pounds.
Petrol is cheeper (Currently less than 60 pl), as is insurance (or it was in dh case, full no claims, brand new car etc paid less than equiv of 200pounds) We pay $175 (approx 80pounds) pw in rent for a large 3 bed (built in robes to all)house, huge gardens, sep kitchen & dining, laundry and self contained annex.
Eating out is cheaper. Clothes are cheaper in some places, but it depends on what you are looking for. I don't spend a greet deal on clothes for dd, and spent $7.60 on a pair of jeans in Target (3pounds).
Our car is a 2006 model and cost less than 8K (uk pounds).
White goods & tv's etc seem to be more costly. We didn't bring our fridge (would have been too small anyway) and it cost 400pounds (which, for it's size isn't actualy that much tbh)
We manage very well on much less than your dh gets, being that we are now permanent residents we are allowed to claim family assistance (which we are entitled to straight away, anything else we have to wait 2 years for, but there isn't anything else we would be intitled to).
