UPDATE 4.35PM: Police say the death of a woman whose body was found at a Caloundra West home appears to have occurred in non-suspicious circumstances.
Results of a post-mortem examination conducted on the woman today were a factor in investigators' determination.
However, they said the investigation would be ongoing.
A crime scene established around the unit remained in place this afternoon.
EARLIER: An elderly resident of Birch Street in Caloundra West has spoken of her fear after a neighbour's body was found in her home by police.
Nola Huntington has lived in the quiet, upmarket street for 11 years without incident.
The quiet was shattered late yesterday with ambulance, police and news crews driving into the small dead end street and cordoning off a duplex only a few homes up from her.
It was only later she heard the shock news one of her neighbours, whose name has not been released, had died.
"They say she had been dead since Saturday," Mrs Huntington said.
Another neighbour said she had heard a noise on Saturday night "like a fight" but no one expected the worst.
"This is a dead-end, quiet street," she said.
"To have something happen like this so close to you, it worries us."
The duplex was still cordoned off this morning as police continued their investigations.
Police are treating the death as suspicious.
A CRIME scene is in place at a Caloundra West unit where a 57-year-old woman's body was found by a neighbour.
Police are treating the woman's death as suspicious as they try to confirm whether or not foul play has been a factor.
Sunshine Coast District Criminal Investigation Branch officer-in-charge Mick Doogue said the woman had not been seen for a few days and was discovered by a neighbour when they went to check on her in her Birch St unit about 3.10pm yesterday.
Detective Acting Senior Sergeant Doogue said the woman had head injuries.
"There is a consideration it may have been an accidental death," Det Act Snr Sgt Doogue said.
But he said police would hold the property as a crime scene until that could be confirmed.
He said the woman lived alone.
A post-mortem examination is expected to be completed today.
