Under the plan, currently on exhibition by the Geographical Names Board, the boundaries between the two suburbs would be shifted slightly, giving New Lambton Heights a handful of new residents from neighbouring Cardiff Heights.

If approved, the properties currently addressed as Currawong Road, Cardiff Heights would become a part of New Lambton Heights.

Lake Macquarie City Council has proposed the change due to Currawong Road being an isolated road with its only access coming from Marshall Street in New Lambton Heights, the NSW Department of Finance, Services and Innovation said in a statement late on Thursday.

Currawong Road is a cul-de-sac that runs parallel to Main Road, with New Lambton Heights to its immediate north.

Announcing the consultation period for the proposal on Thursday, chair of the Geographical Names Board Narelle Underwood said it was important that residents were happy with their regions’ place names and that boundaries reflected usage by the local community.

“An important element of determining place names and boundaries is endeavouring to meet the approval of affected residents, and to reflect local usage and conditions,” Ms Underwood said in a statement.

She encouraged people to have their say on the proposal so the community’s feelings could be measured and assessed prior to a final decision.

“So that it can consider feedback the board is encouraging community comment before it considers adopting council’s proposal,” she said.

Copies of the map (titled, GNB3506-4-A) showing the proposed suburb boundary amendment will be on display at Lake Macquarie City Council office. The proposal can also be viewed and submissions lodged on the Geographical Names Board’s website at www.gnb.nsw.gov.au, or by emailing ss-GNB@finance.nsw.gov.au. Written submissions can be made to the secretary, Geographical Names Board, 346 Panorama Ave, Bathurst, NSW 2795.

Submissions close on August 20.
