A woman whose body was found buried in a shallow grave north of Brisbane had been tortured before her death, police allege.

De facto couple John Harris, 42, and Linda Appleton, 40, of Brighton, have been remanded in custody after being charged with the murder of mother of four Tia Landers.

They have each been charged with three counts of deprivation of liberty, torture, murder, unlawful use of a motor vehicle, interfering with a corpse and two counts of unlawful possession of a weapon.

Harris and Appleton did not appear this morning in Redcliffe Magistrates Court where the matter was adjourned until January.

The body of 28-year-old Ms Landers was discovered in state forestry near Roys Road at Beerburrum yesterday.

She had been reported missing last month.

Acting Detective Superintendent Damian Hansen has told reporters that there was evidence of violence at an address on Newport Street, Brighton.

He said Ms Landers had gone to the address voluntarily and that Harris and Appleton were associates of hers and had known her for some time.

"There's evidence there has been violence at Newport Street," he said.

"We'll be making appeals to anyone ... with knowledge of Ms Landers's movements leading up to June 16 or knowledge of this offence to contact us through CrimeStoppers."

A post-mortem examination was to be conducted on the body of Ms Landers today.

At the time of her disappearance, police said they held serious concerns for her welfare as she had not been in contact with friends or family and had a medical condition.

Friends and family have left tributes to Ms Landers on a Facebook page.

"Rest in peace ... justice will be served! I promise to take care of your beautiful babies," one comment read.
