The ACT Government has vowed to rectify a quirk in the territory which has left it the only jurisdiction without a mammal emblem.

While the gang-gang cockatoo is already the capital's faunal emblem, all states and the Northern Territory have mammal emblems too.

ACT Chief Minister Andrew Barr said community interest in introducing a mammal emblem for the ACT meant a public online vote would be held to determine the best fit.

"I think there is interest in a fairly quick and inexpensive process," he said.

"We can have an online vote on the Yoursay website.

"I know there's a lot of community interest in supporting different mammals from our fantastic region."

Three frontrunners floated by the Government were the echidna, the brush-tailed rock wallaby and the bettong.

In recent years the ACT has been home to a successful breeding program to bolster the numbers of the threatened bettong.

Mr Barr said Canberra played an important conservational role with many native animals.

"Another would be the brush-tailed rock wallaby, there's just 40 left in the wild and Canberra's Tidbinbilla Nature Park is involved in a program to support and protect that species," he said.

"I think technology now allows us to do this in a very expedited and straightforward way and Canberrans can jump online early in 2018 to cast their vote."
