An elderly couple and their adult daughter have died in a suspected murder-suicide at a house on Queensland's Fraser Coast.
Police were called to an address on Riverheads Road at Booral, south of Hervey Bay, following reports of a gun being fired about 6:30am.
Robyn Frescura, 50, was found dead at the property while her mother Rita Janice, 68, and father John, 79, were taken to the Hervey Bay Hospital with critical injuries where they later died.
Police believe Mr Frescura's injuries were self-inflicted, and no-one else was involved.
Detective Acting Inspector David Briese said Ms Frescura was believed to have been living with her parents at the property, and they were long-time residents of the area.
He said someone from the house called triple-0.
Officers seized a gun at the scene and have begun forensic examinations inside the house.
Police said the next of kin had been notified.
Neighbour Robert Marturano said the family had lived at the property for at least 10 years, and he was "very shocked" by what had happened.
"They were just a normal everyday family. The times I'd spoken to John he was quite normal. There was never any ideas or indications anything was wrong.
"My heart goes out to the family ... it's not something you'd wish upon anybody.
"I don't know what has driven him to do this sort of thing, I'm just deeply sorry for the extended family. It's just unbelievable."
In Parliament, Premier Annastacia Palaszczuk offered her condolences to the local community.
The shooting happened as Ms Palaszczuk tabled the Government's latest plan to deal with domestic and family violence.
"On behalf of Queensland, I send my condolences to the Hervey Bay community and I believe that all honourable members would agree with me that this senseless violence has to stop," she said.
Family friend Gwenda Knapp visited the crime scene today.
She told the media Rita and John Frescura had both been diagnosed with cancer.
"They were a caring family," she said.
"It's a sad situation that it ended like this."
Mr Frescura gave an interview to the Fraser Coast Chronicle two years ago after he was given a parking fine while visiting his daughter in hospital after she suffered a stroke.
