The Tasmanian Aboriginal Centre have accused the proponents of a cable car for Mount Wellington of 'ripping off' Aboriginal culture.

The Mount Wellington Cable Car group is now using the mountain's Aboriginal name, Kunanyi, to redirect people to its website.

Last week, the Tasmanian Government introduced a dual naming policy for significant landmarks.

The centre recommended the mountain be given its alternative name.

Kunanyi has now been registered online by the cable car group and a search for the web address 'kunanyi.com' now redirects to its webpage.

A spokesman has defended the move on social media, saying the group prefers Kunanyi to Mount Wellington.

The Aboriginal Centre opposes the cable car plan.

Spokeswoman Heather Sculthorpe says the group's suggestion that its use of the word will improve relations with Aborigines is laughable.

"Dear oh dear, I think we're a bit past that sort of low behaviour. That's quite funny actually," she said.

"We're used to Aboriginal culture being ripped off, there's not much new about this.

"We're not going to give more publicity to the cable car idea, making a public fuss about it."
