Is the Australian accent similar to the cockney accent? [closed]

From my experience the Australian accent is not identical across the entire continent. The differences between the regions are not quite as obvious as you'd notice between regions in a country like the USA, but they certainly still exist.

I would characterise the Australian accent as being distinct in three regions: The East Coast, The West Coast and "The Regions", or Central/Rural Australia (this is of course excluding the very distinct accent of an English speaking Indigenous Australian). The Rural accent is what many within Australia may refer to as a "bogan" accent, that harsh, masculine accent epitiomised by movies like 'Crocodile Dundee'. The differences between the East and West are small but still substantive. The Western appears to have the same roots as the East but its softer, perhaps closer in many ways to its British origins. Within the East/West Coast accents however there is quite large variation, a product of Australian multiculturalism or their specific lived experiences I suspect. The variation in accents they could be exposed to in their formative years probably produces a less rigid outcome, and so it can sometimes be quite difficult to determine what heritage an Australian has or where they call home.

Its therefore very difficult to determine if the cockney accent has had a very heavy influence on any of the Australian accents, as where it might be very prominent in one individuals accent it may not be noticeable in any form in a different individuals accent. My intuition however somewhat leans towards saying it is both influenced and in most cases similar. It would make sense of course for many of the first Australian settlers to have had cockney accents, but in the centuries since the influence of the large number of Irish prisoners and immigrants, as well as the earlier Chinese immigrants prior and post the 'White Australia' Policy and the European immigrants after the World Wars on the accent, the base the distinct sound originates from would have shifted dramatically resulting in the cockney accent being less obvious.

I'm not sure there's an objective answer but my Australian intuition and experience says yes.
