There is no Independence Party in Australia.
Australia does not have a Declaration of Independence, as its path to independence was quite different to that of the United States. See the related question.
Australia did not acquire its independence from the US. The US has never had any claim to any part of Australia. Both countries were initially colonised by Britain, and each, in turn, acquired its independence from Britain.

Australia obtained its national independence in January 1, 1901.
Independence Day is a different date for each country. For example, in the United States, Independence Day is July 4th, but independence is recognized in Australia on January 26th and is called "Australia Day" or "Anniversary Day".
Great Britain
The British Empire.
Prior to Papua New Guinea's independence in 1975, it was administered by Australia.
We don't have an independence day in Australia! We do have Australia Day, which is on the 26th of January. Most people celebrate Australia day by having a bbq with friends, and apparently there are a lot of tennis and cricket matches on Aus. Day... but I'm not really a sport person.
