There are a few reasons why the natural fibres from Australian wool are considered to be of such high quality. First, the vast majority of Australian wool comes from Merino sheep, which produce wool that is finer than that of other breeds.
Australia also has a long history of producing wool, dating back to the early days of European settlement. This means that there is a lot of experience and expertise when it comes to raising and caring for sheep, as well as the processing and spinning their wool.
