How many detention centers are there in Australia?

As of my most recent knowledge update in September 2021, there were 24 immigration detention facilities in Australia. However, this information may have since changed, as the number of detention centers can fluctuate based on various factors such as border protection policies, immigration laws, and the overall migration situation in the country.

To obtain the most accurate and up-to-date information, I recommend visiting the official Australian Border Force (ABF) website, where they regularly publish statistics and updates related to immigration detention in Australia.
