Where is the largest meteor crater in Australia?
1. Woodleigh crater, 120km. The meteorite that hit this site near Shark Bay around 364 million years ago created what is now considered one of the biggest impact craters in Australia. It is also among the biggest in the world, though the crater itself is not exposed at the surface.
Does Australia have impact craters?
In Australia seven distinct craters, ranging in size from about 25m to around 1km in diameter, have been recognised. Five of these are associated with meteorites. In addition, there are another 30 very much larger but deeply eroded and enigmatic circular scars that present some evidence of an origin by impact.
Where did the meteor hit in Australia?
Scientists discovered the world’s oldest meteorite crater in Western Australia’s mid-west earlier this year. The Yarrabubba crater, located near Meekatharra in WA’s mid-west, was found to be around 2.23 billion years old. That makes it over 200 million years older than the next oldest crater.

At Henbury there are 13 to 14 craters ranging from 7 to 180 metres in diameter and up to 15 metres in depth that were formed when the meteor broke up before impact.
Why are there so many craters that are officially considered’unconfirmed’?
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.
