The track, a diversion off the Kiama Coastal Walk through the former quarry's basalt landscape, was endorsed last year following representations from Kiama councillor Warren Steel, who believes it could be a great tourist attraction.

Cr Steel suggested the track be named Thunda, as the name Bombo is an Aboriginal word for 'thunder. However, last month councillors debated whether that was the derivation of the name Bomba, with some saying it was named after the Aboriginal leader Thumbon.

Cr Kathy Rice suggested the name be referred to the streets and reserves naming committee, and said it should be spelt correctly, but Deputy Mayor Neil Reilly said Thunda had marketing potential.

Cr Steel said it was an area, not a street or a reserve. Sydney Water's sewage treatment plant occupies part of Bombo headland, and the rest is held by the Department of Planning and Infrastructure, but is managed by the council.

Cr Steel said the track needed a name.

"We need signs there as a matter of urgency," Cr Steel said.

He hoped the track, a basic trail marked by blue posts, would become a sculpture trail with a lookout on the northern side of the old quarry.

An avid artist, Cr Steel hopes to run a school competition, with a prize for the best name for a cartoon character he drew for the track's marketing and signs.

Cr Steel said he was discussing the matter with senior council staff.

"So many people in Kiama have never been down there - it's fabulous," he said.
