Details of the meeting emerged after a goat was beheaded on Friday the 13th this month at a church in Bellbowrie in western Brisbane.
Melbourne satanist Drew Sinton, who will not be taking part in the Halloween gathering, said the meeting was an act of rebellion and would involve "destructive rituals".
He said Brisbane was an increasingly popular area for satanic cults.
"Queensland is a very Christian state and so holding the meeting in its capital is an act of rebellion," he said.
Balmoral Cemetery in eastern Brisbane, is a regular meeting place for devil worshippers.
Friends of Balmoral Cemetery president Kelvin Johnston said: "I want these people to know that they can do what they want, providing they stay out of the cemeteries.
"They should have respect for people who have other beliefs."
Queensland police said they were aware of the Halloween gathering and would be monitoring the satanists.
Sergeant Barry Bullion, of Morningside, said patrols would be increased around Balmoral Cemetery.
"The episode with the goat was a bit alarming and so we will urge our patrols to be extra vigilant, especially around cemeteries," he said.
Father Adrian Farrelly, of St Agatha's Catholic Church, at Clayfield in northern Brisbane, vowed to take a stand.
"We will combat their actions with the love and understanding of Christ," he said.
The RSPCA warned satanists not to carry out any animal sacrifices.
But Mr Sinton said he was fed up with people thinking badly of all satanists.
"We do have a bad reputation, and I think that's unfair because we are not evil and we do not carry out animal or human sacrifices," he said.
