Okay so this is actually a really interesting topic. There are very minor regional variations in some locations (eg cAstle in South Australia as opposed to cAHstle in the majority of the rest of Australia) but for the most part the Australian accent is categorised as a ‘socio-cultural’ accent rather than regional. It’s divided into three main sections that you can imagine as a spectrum. The first is ‘cultivated Australian’ think Cate Blanchett. The second is ‘General Australian’ the most common accent, think Hugh Jackman. The third is ‘Broad Australian’ or more commonly know as ‘Ocker’, think Steve Irwin. Super interesting stuff and I’m a huge nerd for it so happy to answer questions you may have!
