The cull of 1505 eastern grey kangaroos was completed more than two weeks ahead of schedule, with fewer animals killed than the 1568 forecast.

The Mount Ainslie, Mount Majura and Farrer Ridge nature reserves have now completely reopened, along with East Jerrabomberra Grasslands and Mulligans Flat Woodland Sanctuary.

Goorooyarroo nature reserve remains closed on weekday evenings as a fox and rabbit management program continues.

ACT Parks and Conservation Service director Daniel Iglesias said Canberrans could be confident the cull was completed as part of a broad program of land management.

"Nobody likes shooting kangaroos, however we accept it's the most humane method of kangaroo population management currently available to the ACT government in its role as a responsible land manager," Mr Iglesias said.

Protesters are understood to have attended the reserves in an attempt to monitor the cull. A group of about 50 protesters gathered at the Legislative Assembly in May to voice their opposition to the process.

But Environment Minister Rebecca Vassarotti said she was unable to meet the protesters in good faith, because they fundamentally disagreed.

Ms Vassarotti said in a statement at the time her colleague, Greens backbencher Jo Clay, had met with protesters after she was not able to make a planned meeting.

"I have subsequently met with members of the ACT Greens who were interested in discussing the issue (a commitment that was made at the original meeting)," Ms Vassarotti said.

"Subsequently, animal rights advocates responded by rejecting the veracity of the evidence for the cull, and made a further request to meet to discuss a moratorium on the cull.

"Given this isn't possible and we fundamentally disagree on our assessment of the evidence, I have decided that this subsequent meeting is not something that I can do in good faith."

More than 1900 kangaroos were targeted in last year's cull, which was delayed while an ecological assessment was made on whether the cull was required in the wake of the previous summer's bushfires.

Mr Iglesias told The Canberra Times in May kangaroo populations in urban areas were distinct from kangaroo populations in nearby national parks, where many animals perished in bushfires.

"This particular cull doesn't touch Namadgi kangaroos, nor does it touch Tidbinbilla kangaroos or even the kangaroos that live in the Murrumbidgee corridor," he said.

"These are urban kangaroos. These are kangaroos that are living on these islands that are in the urban footprint, and that are effectively living a life where they have no natural predation."

Mr Iglesias also said in May several hundred carcasses from the cull would be sent to a wildlife sanctuary to help rear endangered Australian animals.

"What we want to do is get to a point where 100 per cent of the animals that we cull, we can reuse in some way," he said, acknowledging previous criticism that the culling program wasted carcasses.

"We've reached out to a number of businesses and we think that in the years to come, it's actually a worthwhile target to try and reuse all the carcasses. We've made good headway this year, we hope we can improve on it again next year."
