Australian slang language option

Like the 'Pirate Speak' but instead consists of heavy Australian slang. An example could be: Whatcha say mate? (Languages). If this doesn't make it to the full game this could be a good April fools update where your screen is flipped upside down, you set on fire if you stay in the sun too long and the language is set to slang. As an Australian, I think this would be funny and inclusive.
