A man accused of torturing and sexually abusing a woman for months at a property in Brisbane's north has been remanded in custody.

Police executed a search warrant on Saturday and allegedly found cash, methamphetamine and marijuana inside a house at Zillmere.

Officers said a woman, who was known to the man, alleged he had been assaulting her in the house over the past three months.

Police charged the 31-year-old man with drug trafficking, torture, seven counts of sexual assault and deprivation of liberty.

The man, who did not appear in court, was remanded in custody during a hearing at Brisbane's Magistrates Court and his lawyer, Adam Magill, made no application for bail.

Mr Magill said his client would be contesting the 29 charges.

"The allegations are quite severe," Mr Magill said.

"He is not taking it well at all.

"I've obviously got some major concerns with respect to his mental health but that's going to be an issue over the next 24 hours that we're going to have looked at.

"He's denying any offending at this point in time and he's given very clear instructions that he'll be contesting all the matters."

The matter is due back in court on July 4.
