Australian and New Zealand Englishes
The vocabularies of Australian and New Zealand Englishes are very similar. Both have been enriched by words and concepts from the hundreds of indigenous languages that pre-dated European settlers, only about 50 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. (From Ask Oxford )
Briefly, Australian English follows the British spelling and has different sounds for some of the vowels.
