Published on Monday, 9 September 2024 at 3:16:49 PM

The Department of Agriculture and Regional Development has announced a significant expansion of the PSHB Quarantine Area (QA) effective from 6 September 2024.

The new QA has increased in size from 871 km2 to 16,400 km2 and now covers the entire Perth metropolitan area. Five additional Local Government Areas are included: Armadale, Kwinana, Mundaring, Rockingham and Serpentine Jarrahdale, taking the number of QA Local Government areas from 25 to 30. The Quarantine Area is divided into Zone A and Zone B.

Zone A covers an area with high numbers of infested trees and where intensive control activities such as tree removal are underway. This zone has more restrictions on the movement of high-risk materials.

Zone B covers an area with fewer or no infested trees and where heightened surveillance is underway to identify and control new infestations. This zone is intended to act as a ‘buffer zone’ between areas of higher infestations and the remainder of the State.
