John Anthony Ryan, 36, was arrested at a house in Coburg early Thursday morning is assisting police with their inquiries.

Police confirmed they found a body, believed to be of Wayne Amey, near the summit of Mount Korong in central Victoria on Wednesday afternoon.

Detective leading senior constable Phillip Gynther, speaking from the base of the mountain, said the body was found about 2pm on Wednesday.

"We were taken there by the gentleman who has been charged with offences relating to the kidnap and death of Mr Amey," he said.

"We've found Mr Amey on the top of the hill, his remains have been placed down in a crevasse between two large rocks."

Although police knew the type of area where Mr Amey was placed, the scale and difficulty of the mountain terrain meant the search had spanned two days.

"It was a difficult spot for this man to recognise exactly where he was placed," Detective Leading Senior Constable Gynther said.

A forensics crew arrived at Mount Korong before 6pm and started working on a rocky outcrop.

It is understood the remains were resting on a crevasse between two car-sized boulders.

Earlier on Wednesday, an ex-girlfriend of Mr Amey appeared in court after it was alleged she helped dispose of his body.

Robyn Jane Lindholm, a one-time girlfriend of slain underworld figure Alphonse Gangitano, made a brief appearance in Melbourne Magistrates Court on Wednesday. She was arrested last week in relation to the disappearance and suspected death of Mr Amey.

Ms Lindholm, of Reservoir, was charged on Tuesday with being an accessory to murder. She is also charged with intentionally causing serious injury to Mr Amey on December 10 and stealing his red Toyota Hilux that same day.

Charge sheets tendered to court allege that some time between December 10 and December 14, Ms Lindholm knew or believed Mr Ryan killed Mr Amey and assisted in the disposal of Mr Amey's body.

Detectives were told the body had been dumped after he was attacked near his Hawthorn apartment on December 10.

Ms Lindholm, a former stripper, wore a black singlet with silver sequins during her court appearance, during which she looked at two women seated at court.

She said nothing and made no application for bail. She was remanded in custody to appear again on May 13.

Defence counsel Juliet Hardy said her client was coming down from using the drug ice, had never been in custody before and suffered from panic attacks and asthma.

Ms Hardy said Ms Lindholm also wanted to see a doctor, as she had suffered several abrasions during her arrest.

Ms Lindholm was taken into custody following a police chase involving Mr Amey's Hilux in Brunswick on Friday.

Torsten Trabert was also charged on Tuesday night with intentionally causing serious injury and accessory to murder.

He faced an out of sessions court hearing on Tuesday and was bailed by a bail justice to appear in the Melbourne Magistrates Court at a later date.

Mr Amey, who owns the Visions Fitness Centre in Hawthorn, could have been beaten and "taken" from his apartment car park in Hawthorn, Detective Senior Sergeant Ron Iddles said.

His son, Pat, found a pool of blood in the car park the next morning and contacted police.

Ms Lindholm and Mr Trabert had been assisting police with the search for Mr Amey, Senior Sergeant Iddles said on Tuesday.

"As a result of the information we're confident that, sadly, Wayne Amey's body is here at Mount Korong."

In 2005 Ms Lindholm's then fiance, George Templeton, also known as George Teazis, vanished after leaving the Reservoir house the coupled had shared.

Mr Amey, who was a personal trainer and dated Ms Lindholm before and after her fiance's disappearance, was questioned by police.

Mr Amey had been separated from Ms Lindholm for several years, and there was ongoing animosity between the couple over a real estate dispute.

Staff at Visions Fitness Centre in Hawthorn declined to comment on Mr Amey's death.
