List of impact craters in Australia
This list includes all 27 confirmed impact craters in Australia as listed in the Earth Impact Database.[1]
Impact craters - confirmed
Unconfirmed impact craters
Main article: List of unconfirmed impact craters on Earth
The following craters are officially considered "unconfirmed" because they are not listed in the Earth Impact Database. Due to stringent requirements regarding evidence and peer-reviewed publication, newly discovered craters or those with difficulty collecting evidence generally are known for some time before becoming listed. However, entries on the unconfirmed list could still have an impact origin disproven.
