I'd be happy ta help. It's not that hard. It depends on how strong the bloody accent is. I was yacken to this (starts with bast ends in ard) the 'smorning, and he's accent was piss weak!
LOL, like I said in that little paragraph, it defends on how stong the accent is. If you have your character in a city then the accent will be weaker because of the multi-culturalism. I grew up in small towns and visited me granddad who is a farmer. My accents stronger then most at my school. I now live near beachy's and their accent is medium. They have more of a surfers speach.
(that word again)- is a common word used to refer to mainly guys and isn't always meant in an insulting way.
The F word- if you want swearing in your story, the f word is common amount labourers more the scolers.
bludger- does not mean evil ball bent on killing quidditch palyers but a lazy person.
G'day- Not many Aussies can actually say Good Day. It sounds weird.
'smorning- this morning.
Like xOxLyDzxOx said, you can alway PM an Aussie. I wont mind at all.
