Detective Acting Inspector Alina Belle confirmed that the pair were married, and their wounds were consistent with gunshot wounds.

“This is not only a tragic occurrence for friends and family, it also significantly impacts the whole of the community,” Belle said.

A neighbour told 7NEWS that the couple’s nine-year-old daughter had allegedly run to her house, saying her dad had told her to run to the neighbour’s house and stay there.

“We don’t believe she was present during the incident or witnessed any part of it; however, that doesn’t take away from how traumatising that will be for that child, family members, and friends,” Belle said.

Police said the couple were not known to police and had no history of mental health issues.

They also confirmed the man was a registered firearm holder.

The deaths are reportedly being treated as domestic violence-related.

There is no ongoing threat to the public, and police are urging anyone with footage or information to come forward.
