Their accent sounds similar to the British accent
Answer
The Australian accent sounds nothing like any British accent to both the British and of course Australians, except perhaps for private school educated "toffs". The Australian accent is as different from mainstream British as US accents are.
In addition:
The Australian accent has been scientifically proven to be one of the most difficult accents in the world to accurately reproduce (seriously). There are also regional differences.
The Australian accent is also nothing like that portrayed by people pretending to be Australians on US television shows. It is not a "cockney" accent with the emphasis on the "oi" sound that it is propounded to be. Where Americans emphasise the "r" in words such as "teacher" and "neighbour", in the Australian accent it is more of a "schwa" (an unstressed, neutral, toneless vowel sound) so it comes out as "teacha" or "neighba" (unstressed).
Additionally:
Australians' (and New Zealanders', with the exception of some Scots accents from Southland/Otago) accents are non-rhotic, where "r" is not heavily pronounced, particularly in the last syllable. They are by no means unique, and some US accents are also non-rhotic.
Watermelon, Australians just have an accent.
their accent?
Australians do not speak in a peculiar cockney accent. Australian English has its own distinct accent and dialect that has evolved since the first settlement of the country. While there may be some similarities due to historical connections with England, Australian accent is influenced by a variety of factors including Indigenous languages, immigrant communities, and isolation from the UK.
In 1915, Australians spoke much as they do now, but without the influence of the American accent and slang.

Yes, Cuban Spanish has a unique accent, just as each Spanish-speaking country has its own distinct accent.
The simple answer is because they are not British! Australians developed their unique accent because of the accents of the original settlers (who came from various parts of the UK but with a high concentration of Londoners and Irish) and the unique social setting of the penal colony and the subsequent change to an agrarian economy.
