Oopsy, Eralc! you can't buy alcohol on Good Friday either - apparently it's the one day in the year that no bottleshops are open! DH is a tad miffed because we went to the EAster Show yesterday afternoon (BIG mistake) and we got home too late to do anything about the wine situation.
Things I love about Australia that are different to the UK:
the beef sausages. I don't do pork, it makes me ill, and I'm wheat intolerant - so knowing that sausages here are routinely beef with rice flour makes my life much better. 
Also the spelt bread - it's a sliced loaf that doesn't go rock hard within 2 days - I like that.
And the rice crackers - different brands, even! Sakata did come to England but pulled out again after a while, sadly. And Jacobs' (or whoever it is who did Thai bites) put fucking wheat flour in their rice crackers!
Mind you, over here, Uncle Toby's put wheat flour into all their breakfast cereals apart from porridge, so no oatbrites for us either (thanks a bunch for that). Means we bring 8 boxes of Oatibix back from the UK whenever we go.
In the UK, I mostly ate red leicester cheese. I buy the organic cheddar; can't even remember what UK cheddar was like now but I've never been a fan of ultra-strong stuff anyway, gives me acid reflux. I do miss a decent range of nice cheeses though - I have only found 3 organic cheeses so far - mild cheddar, edam and gouda. Could get loads more than that in the UK. Including decent mozzarella - oh GOD - the MOZZARELLA!!
Don't, if you value your stomach, buy the hunk of mozzarella - if you want proper Italian style mozzarella, you need to buy the Bocconcino stuff. the other stuff is only any use for putting on pizzas.
