Three children ran to their neighbours to raise the alarm after a 52-year-old man and 40-year-old woman were found dead in a suspected murder-suicide.
The tragic discovery was made about 6.30 AEST on Tuesday morning at a property in the northern Gold Coast suburb of Pimpama.
Authorities confirm the young children were in the home at the time of the incident, who alerted neighbours before police arrived.
Authorities were initially called to the scene following reports of a disturbance, but a neighbour said they hadn't heard anything in the hours before the gruesome discovery.
"We didn't hear anything or see anything,' a neighbour told The Courier-Mail.
"A little bit scary ... it's very quiet. There's nothing really ever happening, there's no commotions, so this is a pretty crazy thing to have happened."
Police are treating the deaths as suspicious in the early stages if their investigations.
"Enquires are in their infancy," Detective Inspector Mark Thompson Gold Coast Criminal Investigation Branch said at the scene.
"They were known to each other and we do not believe a third party was involved."
"There doesn't appear to be any firearms or weapons of that nature to have been involved in this offence," Mr Thompson said.
Paramedics were called to the scene, but an ambulance spokeswoman told Daily Mail Australia that no one was required to be transported to hospital.
Police have established a crime scene on the street as forensic investigators look for clues to what led to this fatal incident.
