ACT Environment Minister Mick Gentleman announced $1.6 million for the construction of an ecotourism learning centre at Mulligans Flat, while almost $600,000 will be spent on the eradication of rabbits and hares from the area.

The visitors centre was previously outlined as part of a 2016 election commitment by Labor.

It's hoped the centre will bring in more tourists to the area and act as a gateway to the wildlife sanctuary.

The centre is expected to be open to the public during the 2021-22 financial year.

Woodlands and Wetlands Trust chief executive Jason Cummings welcomed the funding.

"It's long been an aspiration of our organisation and members to develop a world-class facility that brings together community, conservationists and researchers, where they will be able to work together," he said.

"It would absolutely boost numbers and would be a great asset and hopefully attract more visitors."

The $1.6 million announcement matches funding already raised by conservation organisation Odonata.

Mulligans Flat is the only woodland area in Australia that is predator free and protects endangered species such as the eastern bettong.

Mr Cummings said the three-year funding to rid the sanctury of rabbits and hares was step in the right direction. He said while there isn't a large rabbit population in Mulligans Flat, it has the potential to become a larger problem in years to come.

"If rabbit numbers are unchecked, it would impact significantly on native flora and can do untold damage to the vegetation," he said.

While rabbits were eradicated from the sanctuary in 2017, the new program will help remove the species from the new area in Mulligans Flat, which extends to the Throsby offset area and the Goorooyarroo Nature Reserve.

The program will involve monitoring rabbit activity, establishing a network of rabbit fences as well as baiting and fumigation.
