A QPS spokesman later told news.com.au it "wasn't a very nice discovery" for emergency services.
Since Mr Peachey's comments, an undertaker has been called to the home to remove the bodies.
Police were unable to confirm the relationship of the two found and said they were working to notify the family.
"No positive identification has been made," he said.
"We have our suspicions but until we are able to do a positive identification, to be fair to the family, we will not be releasing anymore information."
Detectives are also in the process of gathering information from neighbours and witnesses in the usually quiet suburban street.
"At this stage we've only briefly spoken to the neighbours … I don't want to speculate on what they've heard or what they may have heard so far," Mr Peachey said.
The two deaths are being treated as suspicious however police said they were yet to bring anyone into custody.
Police have not revealed the cause of death and would not say if firearms had been involved.
