Police searching for a man's decapitated head have identified several key locations of interest near a coastal town.
Authorities have been unable to find the entire remains of Julian Story, 39, after his dismembered body was discovered at Port Lincoln in South Australia on June 19.
Tamika Sueann Rose Chesser, 34, a former Beauty and the Geek contestant, has been charged with his murder.
Detective Superintendent Darren Fielke said information received by the investigation team coupled with the use of specialist equipment has identified several additional search sites around Port Lincoln.
"New search areas have been identified and by undertaking these renewed searches, we hope to find Julian's missing remains, which will give comfort to his family and allow them to peacefully lay him to rest," he said in a statement on Tuesday.
Police searching for Mr Story's head has spanned Port Lincoln reserves, parks, bushland, the ocean, pier and bay areas and involved state emergency service volunteers, water police, divers and local patrols.
Previous searches were paused on July 1 as police reviewed CCTV footage to pinpoint the movements of the ex-reality TV star accused of his murder.
Police found Mr Story's body after firefighters were called to a Flinders Highway property to investigate reports of a blaze.
Chesser, who police said had been in a relationship with Mr Story for several months, was arrested on June 19 after Mr Story's body was found at the couple's home.
She was known to walk through back streets and parks in the Port Lincoln area with her dogs.
Authorities are appealing for video from members of the public that might help the police investigation.
