Explanation:
The main difference to note is how we pronounce vowels, Australians put emphasis on the "ee" sound whilst Kiwis love the "u" sound, for example Aussies tend to say "Feesh and Cheeps" whilst Kiwis will say "Fush and Chups", Aussies will say "Seedney" (for the city Sydney) whilst Kiwis will say "Sudney"
