Gregory John Hudson arrived on the Gold Coast on Monday, and was staying with a friend at the Mulgrave Crescent unit where he his body was discovered.

Detective Superintendent Dave Hutchinson said police wanted to hear from anyone who had any contact with Mr Hudson over the past four days.

"We definitely know that since his arrival on Monday he has moved around the Gold Coast, he has used taxis a fair bit," he said.

"We're not exactly sure where he's been, and that's one of the reasons we'd like to be able to pinpoint his movements and people he's been with."

Forensic officers were still combing through the scene, but Det Supt. Hutchinson scotched rumours that Mr Hudson had been found bound to a chair by his friend.

"I'm not going to go into any specific detail in relation to the crime scene," he said.

"Obviously there are some things in there that for operational reasons we don't want released, but I can certainly confirm that he wasn't found tied to a chair."

Det. Supt. Hutchinson said police had spoken to two people including one woman taken from the scene, but refused to confirm if she was a sex worker.

"I don't think it's really appropriate for me to be discussing their personal circumstances," he said.

"They're not suspects and they're currently assisting us with our inquiries."

Det. Supt. Hutchinson said Mr Hudson was not married, and police were liaising with his family.

An autopsy was carried out on Friday, with the case treated as a suspicious death until further investigations are completed.
