The survey, which will cover the entire state with the exception of heavily forested parts of east Gippsland, will provide information about the abundance and status of kangaroo populations.

It is also hoped it will enable a better understanding of the distribution of the eastern grey kangaroo, the western grey kangaroo and the red kangaroo.

Helicopters will fly about 200 feet above the ground, at a speed of 50 knots.

The Department of Environment, Land, Water and Planning says an aerial survey is the only feasible way to estimate population sizes of the animal, given the large area that needs to be covered.

The department says the survey will help it ensure its kangaroo management activities are sustainable.

The survey will start on September 11 and continue until September 30.
