Australia has many cultures within it and most of them are fairly well isolated from each other as the result of racism and xenophobia. so tends to be a bit of a cultural wasteland depending upon the united states for its cultural moores and attitudes.
The above answer does not accurately address the question or consider what a cultural hearth is. A cultural hearth is a locality from which which major cultural influences were or are generated. Historically, major cultural hearths are places such as Mesopotamia and West Africa. For this reason, Australia could be considered a minor cultural hearth because the aboriginal culture is completely unique and not replicated anywhere else in the world.
The difference is that, normally, many ideas and innovations that begin in cultural hearths spread to other parts of the world. In this regard, Australia is a cultural hearth, as some unique Australian inventions and innovations have been implemented around the world. On the other hand, they do not have a uniquely recognisable "Australian" tag to them, and are not always associated with what is Australian.
One example of a cultural hearth is Mesopotamia, located in modern-day Iraq. It is considered one of the earliest cradles of civilization, where the Sumerians developed early forms of writing, agriculture, and urban societies that influenced neighboring regions and beyond.

The process by which cultural traits expand outwards from their source area or cultural hearth is known as cultural diffusion. This can occur through various means such as trade, migration, conquest, or communication, and can lead to the spread of ideas, technology, language, and customs from one culture to another.
