In Oz, the most common form are safety matches that wareami describes.
matchbooks are not common, they're normally used in restaurants, motels etc.
The safety matches here are pretty cheap, I think 1AUD for a 10pak stack from memory, at supermarkets. Several brands available.
The books don't have much RP, the safety kitchen matches do, even though theyr'e honey combed.
I've got a box of safety matches from back in the early eighties (I'd guess), it's magnificant, there's way more RP on it. The matches strike better, it feels soft when striking sort of.
