I find this thread depressing.
You didn't really move halfway around the world to find "little Britain" did you?
I assume the move to Australia was for an improved life for yourself and your dc which would be a lower population/crime rates/better school choices and the weather.
I can understand missing aspects of "home" like favourite supermarkets and television programs etc but the general consensus on this thread seems to be that you want everything UK brought over here. I don't get it???
I live in a suburb of Brisbane where a majority of UK immigrants choose to settle. I have some lovely friends who miss aspects of the UK but love their new life here. The one who didn't moved back after two years and is happier than ever in the UK.
As soon as you stop comparing Australia to the UK you might not feel so disappointed. You have chosen to live in a new country. It means change.
I do agree with you about M&S. Only the food though as I thought the clothes were expensive and crap.
The quality of most food in the Uk was superior to Australia. Except fruit.
I don't agree with alcohol in supermarkets. Access does not need to be made easier for people to consume even more of the stuff.
The huge distance to Australia and within the country is a contributing factor to the expense of items such as books.
fwiw I am desperate to move to the UK but dh refuses.
