The immediate backdrop is the wider regional security crisis that accelerated after coordinated US and Israeli strikes on Iranian nuclear and military infrastructure in March 2026, and Iran’s documented retaliatory operations that followed; those strikes and responses sharply raised Australian intelligence assessments of risks to defence-related events and foreign delegations in 2026.
Domestically, the Land Forces International Defence Exposition had been scheduled to take place in October at the Perth Convention and Exhibition Centre well before the current parliamentary debate, and Western Australian authorities had already moved to plan policing and venue security for a large international defence trade show.
Western Australia’s parliament has approved a bill granting police extra powers to secure the Land Forces International Defence Exposition in Perth, clearing legislative hurdles after a marathon sitting.
The Land Forces Event (Special Power) Bill 2026, introduced by WA Labor and carried with the support of the Liberals and One Nation, authorises special powers intended to bolster policing and security arrangements around the October exposition at the Perth Convention and Exhibition Centre (per smh.com.au).
Greens MLC Sophie McNeill pressed detailed questions that extended debate late into the night, highlighting parliamentary friction over civil liberties and the scope of the measures (per smh.com.au).
The state has already earmarked $11.5 million for security this year, a funding commitment the bill complements by legalising expanded operational powers for police during the event (per smh.com.au).
Proponents argued the measures are necessary after widespread protests disrupted the 2024 Land Forces event in Melbourne, when activist groups combined to impede the show; opponents, led in part by Greens scrutiny, raised concerns about the breadth of special powers and oversight in peacetime policing contexts (per smh.com.au).
The bill’s passage signals that WA authorities plan a tightly controlled security posture for the October expo; lawmakers backed the package across party lines, while parliamentary questions show there is still active concern over protections and limits on enforcement actions (per smh.com.au).
Next steps include implementation planning by police and event organisers to translate the new legal powers and the $11.5 million budget into operational security arrangements for the Perth Convention and Exhibition Centre in October (per smh.com.au).
