"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.
