There's thought to be over 560 wallabies living on the Island.
That's according to the Manx Wildlife Trust, who carried out a survey earlier this year using thermal imaging.
They looked at over 400 hectares of the Ballaugh Curragh, which showed an average number of 568 wallabies.
Manx Wildlife Trust CEO Leigh Morris says they're 100% confident in the numbers, and there were far more counted than they were expecting.
The full report along with a film documenting the survey can be found here.
