Reimagining our iconic landmark

THE future of one of Mount Gambier’s most iconic natural landmarks is now open for public input, with the City of Mount Gambier endorsing a draft Umpherston Sinkhole/Balumbul Master Plan for community feedback through a public consultation period open until April 24.

The draft Master Plan provides a framework to guide the restoration, management and sustainable use of Umpherston Sinkhole/Balumbul, with a focus on environmental stewardship, improved visitor experiences and providing the opportunity for respectful cultural storytelling.

It recognises the site’s significance to both the local community and visitors, and its important role in Mount Gambier’s natural and cultural identity.

The draft Master Plan was developed by Taylor Cullity Lethlean (TCL), supported by a multidisciplinary team with expertise in landscape architecture, urban design, architecture, engineering, lighting, tourism and wayfinding.

City of Mount Gambier General Manager People, Place and Liveability Chris White said the Master Plan balances protection of the site’s unique values with opportunities to enhance how people experience it.

“Umpherston Sinkhole/Balumbul is one of Mount Gambier’s most treasured natural places, and the draft Master Plan provides options to protect its environmental and cultural significance and support community activities while improving the overall visitor experience,” Mr White said.

The draft Master Plan presents two concept options, designed to celebrate the site’s existing character while improving access, parking, pathways, navigation and storytelling.

The first option shows a bold level of intervention, which would position Umpherston Sinkhole/Balumbul as a major visitor destination of statewide significance.

The concept focuses on revitalising the sunken garden as the centrepiece of the reserve, with upgraded paths, terraced seating, new stairs and a visitor centre with lift access to provide inclusive entry to the sinkhole.

Supporting infrastructure would include a welcome pavilion, expanded car parking, improved wayfinding and enhanced landscaping centred on a garden walk.

The second option takes a lower intervention approach, with the sinkhole remaining the central feature, with upgrades including an expanded car park, a small visitor centre with public amenities, and a viewing deck with lift access to improve accessibility.

“Council recognises the strong community connections to this special place, and we are particularly interested in hearing the views of the community in connection with the proposed landscaping and planting treatment of the sinkhole itself,” Mr White said.

City of Mount Gambier Mayor Lynette Martin said community feedback would be central to shaping the final Master Plan.

“Umpherston Sinkhole/Balumbul is a place of deep meaning for our community and a standout experience for visitors to Mount Gambier,” Mayor Martin said.

“By opening this draft Master Plan for public consultation, we are giving the community the opportunity to help guide how this special place is protected, enhanced and shared into the future.”

Public consultation includes an online survey available at haveyoursaymountgambier.com.au/umpherstonsinkholebalumbul along with on site displays at Umpherston Sinkhole.

Council officers will also be available for discussions and on site walks with community and interest groups throughout the consultation period.

All feedback received will be reviewed as part of finalising the Master Plan.
