Tama development may threaten Aboriginal heritage

A large sandstone block may dislodge and collapse as a result of the development of a property at the back of Tamarama Gully.

There is potential risk of damage not only to the property below 362 Birrell St, but to Aboriginal heritage in the undercut cliff below should excavation for a newly-proposed basement commence.

“If the excavation cracks or weakens the sandstone, without further study there is belief in the community it may actually loosen the boulder,” said Waverley Councillor Dominic Wy Kanak.

“If it weakens it severely, it could break or crack, and maybe fall on top of the potential Aboriginal cave. Or in the more severe situation, crack and fall towards the property on 364 [Birrell St].

“From my point of view as an Indigenous councillor, we need to properly assess Aboriginal heritage in the Waverley Council area.”

CEO of the La Perouse Aboriginal Land Council, Chris Ingrey said they were aware of the sandstone rock shelter located at the gully.

“[We] believe, based on the landscape and surrounding sites, that there is potential for objects of cultural significance to Aboriginal people to be present within the shelter,” he said.

Council voted late last year the property owner engage an archaeologist experienced in Aboriginal site investigation to assess the site prior to the commencement of construction work. But the extent of the land council’s involvement in this assessment is uncertain.

362 Birrell St adjoining Tamarama Park was formally subdivided in 2011 when Council purchased the rear block for open space. Community opposition to development on the front block – currently a single-story house – coincided with approval to build a two-story house. Restrictive covenants were placed on what could be constructed.

An application for amendment to the originally approved development was made late last year. It sought to increase the building envelope, install a lift and a new basement. The application for increase of the building envelope was withdrawn.

However the revamped plans were approved and extra excavation will occur as a result of the new concerns.

Deputy Mayor Tony Kay said in a statement: “Waverley Council has an ongoing commitment to legislation in respect to Aboriginal heritage, which is being applied via the conditions of consent recommended for this development.”

The archaeologist report is expected to reach Council in coming weeks.
