Four sites on NSW's far south coast will be known by dual names in recognition of the local Yuin nation. 

Following public consultation, the state's Geographical Names Board officially assigned the dual names of Gulaga for Mount Dromedary, Biamanga for Mumbulla Mountain, Barunguba for Montague Island and Najanuka for Little Dromedary Mountain using the local Dhurga language.

For Bunja Smith, a Walbunja Elder and Chair of the Biamanga and Gulaga National Park Board of Management, it is a welcome decision.

"It's hard to describe the elation you feel when you see your culture put up-front," he said.

"It has a reconciliation theme because we've kept both names … but I believe the trend will occur where they start using the Aboriginal name."

The NSW National Parks and Wildlife Service said both names have equal status and are considered official names.

Signs, maps and directories will feature both names and the signage in each park will be updated accordingly. 

Mr Smith said the change will come naturally.

"If I walked down the street in Narooma and I asked 10 people who Montague was, they couldn't tell me," he said.

"But if I mentioned the word 'Barunguba' to them, I reckon I'd spark some interest.

Aboriginal name to come first

Public feedback on the proposal to dual-name the four sites opened in June and July this year.

The names are set to be updated at each site over the next six to 12 months.

NPWS Eurobodalla Area Manager Paula Tomkins said the public can also expect to see the new names updated on maps.

"For the first time, dual-name sites in the state will be recorded on the NSW topographic maps using the Aboriginal names first," she said.

Ms Tomkins mirrored Mr Smiths belief that the dual names will be embraced by residents in the Eurobodalla and Bega Valley.

"The community are being really positive about it," she said.

"Over time, these names have been used more often anyway so it's almost a natural progression."
