Australian English - The vocabularies of Australian and New Zealand English are very similar. Both have been enriched by words and concepts from the hundreds of indigenous languages that pre-dated European settlers, only about fifty of which continue as first languages. The line between formal and informal usage is perhaps less sharply drawn in Australasian English than it is elsewhere: suffixes such as -o and -ie, giving us expressions such as arvo (afternoon), reffo (refugee), and barbie (barbecue), are freely attached to words even in more formal contexts.
