It's all in the pronunciation.
We're really that easy.
I will give you some examples.
This is pronounced Oz (as in the Wizard of Oz) + e (the letter e)
This is pronounced e (the letter again) + mew (the word for the sound cats make)
Ignore the spelling, it is pronounced Mel + b'n (like 'bun' but without the u)
Armed with this secret knowledge you can instantly be proclaimed a good bloke/blokette, be included in shouts at the pub and can get Australians to like you!
Unless you're a bit of a twonker.
In which case you're on your own.
