It doesn't matter how good your English is or how perfectly British your pronunciation sounds because if your dream is to fly to Australia you may have a hard time understanding Aussies (as Australians call themselves)…Yes, because Australian slang is very rich and tends to shorten almost everything. Do not you believe it? Here is a proof!
Anyone who encounters Australian slang for the first time seems rather surprised how sweet it sounds because it sounds like kids’ language: “I’ll cook barbie with mushies. Bring a coldie for my mate, please.”
Using shortened words has become Australians’ national unique feature for more than three centuries! The earliest appearance of clipped forms in the written language dates back to 1800s, and this tradition is still thriving according to the number of words, sayings and even phrases used in the Australian conversational language.
Unlike British or American slang, Australian slang terms are more recognized for their abbreviations than phrases, but that’s only for the foreigners. No matter what Aussie city you visit, from Melbourne to Victoria, most likely you will hear at least a dozen of the following phrases since all Australian phrases are not restricted to a specific region and are universally used across the country.
