A coroner and representatives of the victims of the Wieambilla shootings that claimed six lives have visited the crime scene as part of preparations for an inquest.
Queensland State Coroner Terry Ryan is investigating the shooting deaths of two police officers and four other people at Wieambilla on the Western Downs on December 12 last year.
Counsel assisting Ruth O'Gorman KC revealed on Thursday as part of a pre-inquest conference that the visit had taken place last month.
"The idea of a site visit prior to the inquest in order to understand the layout of the site was supported by a majority of the parties," Ms O'Gorman said.
All interested parties in the investigation who wanted to take up the opportunity, as well as Mr Ryan and his staff, visited the property in remote farmland and attended an on-site briefing by police Ethical Standards Command investigators.
Constables Matthew Arnold, 26, and Rachel McCrow, 29, were wounded then fatally shot at close range within 10 minutes of entering the property for a welfare check on a missing person.
The three suspects in the shooting, Gareth Daniel Train, 47, Nathaniel Charles Train, 46, and Stacey Jane Train, 45, lit fires in an attempt to flush out a female officer who escaped being shot after taking cover.
The Trains' neighbour Alan Dare, 58, was shot dead when he attended the property to investigate the fire.
The three suspects were later shot dead during a confrontation with heavily armed officers from the police's Special Emergency Response Team (SERT).
Ms O'Gorman told the conference in Brisbane Magistrates Court on Thursday that reports from investigators and experts were due by early next year.
The Coroner's Court itself has tentatively booked four weeks from July 29 to August 26 in 2024 for inquest hearings, with the parties involved having until December 20 this year to raise any concerns about the proposed timing.
Ms O'Gorman said investigators were still pursuing a line of inquiry and parties should have reports on their findings within the next four months.
The interested parties, which include the Queensland Police Union, the families of the deceased officers and SERT members, have provided to the coroner lists of concerns and issues they would like raised during the inquest.
Those concerns have also been provided to the police's Ethical Standards Command investigation.
The matter was adjourned to another pre-inquest conference due to be held on May 21 next year.
