List of impact craters in Australia
World map in equirectangular projection of the craters on the Earth Impact Database as of November 2017 (in the SVG file, hover over a crater to show its details)
This list includes all 27 confirmed impact craters in Australia as listed in the Earth Impact Database.[1]
Impact craters - confirmed[]
class=notpageimage|
Locations of confirmed impact craters in Australia, maximum ages: Cenozoic Mesozoic Paleozoic Precambrian
Unconfirmed impact craters[]
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.
