Woodside Energy started legal action against the Disrupt Burrup Hub campaigners in late 2023 following a series of high-profile protests targeting the company.
It demanded that Kristen Morrissey, Emil Davey and Joana Partyka hand over potential evidence relating to the release of stench gas in Woodside's Perth headquarters in June of that year.
The case, which has been slowly progressing since a summons was issued to the trio in December 2023, has been relisted for a hearing on July 16, according to the Western Australian Supreme Court.
''This is yet another blatant attempt by Woodside to threaten, intimidate and silence peaceful young campaigners sounding the alarm about their gas expansion," Mr Davey said in a statement.
Described as a hoax gas leak and stink bomb, the incident at Woodside's offices forced the evacuation of about 2000 staff members, as emergency services rushed to the scene.
The three pleaded guilty in a Perth court to creating a false belief, with Morrissey also admitting to a charge of causing poison to be administered. In July 2025, they received penalties ranging from suspended jail sentences to performing community-based work orders.
Woodside is seeking access to all documents "relating to the description of any person involved in the planning, preparation and/or execution of the incident".
The 2023 summons also calls for the three activists to face the court "to be examined in relation to the description of the potential parties".
Disrupt Burrup Hub also targeted in 2023 the home of then Woodside chief executive Meg O'Neill with an ABC Four Corners camera crew in tow, in a protest that was criticised as extremist and threatening.
It was part of a series of actions against the company that resulted in criminal charges being laid against multiple protesters.
A Woodside legal letter previously seen by AAP from 2023 stated that the company had suffered lost productivity and other damage as a result of Disrupt Burrup Hub's activities.
The upcoming court hearing is listed as an application, but it is not known what it is for.
The Burrup Peninsula, located in WA's Pilbara region and known as Murujuga to traditional owners, contains the world's largest and oldest collection of petroglyphs.
Disrupt Burrup Hub claims Woodside's operations in the area and its proposed expansion will significantly harm the environment.
