Commonwealth English (question for Canadian, Australian posters & so on)

I forgot z/s in words like recognise...

This is a misconception, but a very common one. A preference for 'ize' over 'ise' is not American in origin, even if it is universal in America and the minority option in Britain. It is a somewhat older form and the one traditionally preferred by those with an Oxford education.

And some unique Australian differences:

Verandah is spelled with an H
Program instead of Programme
Footpath instead of Pavement or Sidewalk
Capsicum instead of Pepper/Bell Pepper
Lollies instead of Sweets of Candy
Overseas instead of Abroad
Paddock instead of Meadow and Field
Bush instead of Woods

Literally none of these are unique to Australia.
