The company seeking to build a cable car to the summit of the mountain behind Hobart has emerged victorious from a dispute with an opponent over a "confusingly similar" website that was highly critical of the project, with an almost identical web address.

The Mount Wellington Cableway Company (MWCC) objected to the Australian Domain Administration (AUDA) that the mtwellingtoncablecar.com.au address was too similar to that of its domain mtwellingtoncablecar.com.

A dispute resolution hearing found the website, operated by South Hobart resident Louise Sales, was "confusingly similar" to the MWCC's corporate website.

The hearing found while there was no suggestion the use of the lookalike website was to "make money", the opposition website was "not making a legitimate non-commercial or fair use of the domain name" and that the activity of the site amounted to "disrupting the business or activities" of the MWCC, in "bad faith".

It said a viewer of the opposition website "would be able to work out after a while" it was not the official corporate website of the MWCC, but that they would be "confused for some time", which was the "intended effect".

The sole mediator ordered the website domain be "transferred" to the MWCC.

Ms Sales said even though she had lost the domain name battle, she would not give up.

"The website is still up, it's just under the mtwellingtoncablecar.org domain name ... the website is identical, we've just moved it," she said.

In a statement, MWCC chief executive Adrian Bold welcomed the ruling.

"The decision upholds that we abided by the rules put in place by the Australian Domain Administration and had every right to protect our business.

"We want people to be able to go to our website — mtwellingtoncablecar.com — to learn about the project and not be diverted to a fake site or misled by fake emails with false information."

The web developer behind the lookalike site, Bernard Lloyd, said he was seeking legal advice as to the way forward.

"We have 10 days in which to make a decision on whether we will appeal it in a court," he said.

"It's just a dispute resolution mechanism, its not a court decision."

However, Ms Sales, who has a background in environmental activism, said a court challenge was unlikely.

"Personally I don't think it's realistic," she said.

"If you're looking at a Supreme Court challenge, that could be $100,000, which obviously I don't think either of us have the funds to lose."

Mr Lloyd said he and Ms Sales launched the website because they were angered over the MWCC's purchase of a number of different domain names such as nocablecar.com and respectthemountain.com.au.

Mr Lloyd strenuously denied any suggestion he had "sent anyone any fake emails" and refuted Mr Bold's assertion about the opposition website's purpose.

"The website does not collect email information, has no forms to fill in to collect email addresses ... I have no idea what he is talking about, but it is not us."

Mr Bold previously told the ABC the names were bought for "potential future business opportunities and to ensure they are not taken by competitors".

MWCC also registered names featuring the Aboriginal name for the mountain, kunanyi — an act which angered a local Indigenous group.

Mr Lloyd said the MWCC had bought such domain names to stop community groups from using them.
