A major fire at a luxury waterfront property in Sapphire Beach near Coffs Harbour has become the focus of a police investigation after emergency crews were called to the scene.

The large residence, located on the Coffs Coast, was heavily damaged after flames spread through the property. Fire and emergency crews attended the site and worked to control the blaze, with firefighters returning later after the fire reignited.

Authorities confirmed the property was vacant at the time of the incident and there were no reports of injuries. Police are treating the circumstances surrounding the fire as suspicious and have begun investigations to determine how the blaze started.

The property attracted attention because of its size and location. The luxury estate had previously been owned by prominent figures and was known as one of the region’s significant high-value homes. The site included extensive facilities and was part of a proposed redevelopment project approved by local authorities.

Emergency services responded quickly after reports of the fire, with crews working to prevent further damage and secure the surrounding area. Firefighters monitored the property after the initial response because of the size of the structure and the possibility of remaining hot spots.

Police investigations into suspicious fires typically involve examining evidence from the scene, speaking with witnesses and reviewing available information to establish whether the fire was accidental or deliberately started.

The incident has attracted attention from residents in the Coffs Harbour area, with concerns about property safety and the impact of criminal activity on local communities. Sapphire Beach is a coastal suburb north of Coffs Harbour known for residential properties, beaches and tourism activity.

Local authorities and emergency services continue encouraging residents to report suspicious behaviour and remain aware of community safety issues. Investigations remain ongoing, and further information may be released as police continue their work.

The Coffs Coast region relies heavily on tourism, property investment and local businesses. Events affecting major properties can attract attention because they may influence local development plans and community discussions.

While the investigation continues, authorities have not confirmed any suspects or the exact cause of the fire. Police are appealing for information from anyone who may have noticed unusual activity around the property before the incident.

The fire highlights the importance of rapid emergency response and ongoing community cooperation in helping authorities investigate serious incidents across regional New South Wales.
