Procedures for rangeland condition assessment in the Kimberley 2025
This report defines the procedures used in 2025 by DPIRD to complete rangeland condition assessment (RCA) in the Kimberley region which has grass-based pastures. For the rest of the pastoral estate, DPIRD uses the Procedures for RCA in the Pilbara and southern rangelands which have predominantly shrub pastures.
RCA is the process DPIRD uses to make systematic, station-level assessment of rangeland. Rangeland condition considers both the condition of pastures (as defined in the \u27Pasture condition guide for the Kimberley\u27) and soils as determined by erosion, using the erosion assessment method on pastoral lands in Western Australia. The methods have evolved over several decades of practice and are unique to WA.
RCAs generally report on pastoral stations, which may contain one or more pastoral leases and, on occasion, include land with other tenure types that is used for pastoral purposes.
The data collected during an RCA are used to report on rangeland condition at the station and regional scales. The RCA aims to quantify the condition of rangeland landscapes and pastures and to use this and other information to assess the effectiveness of pastoral management. The RCA process is part of DPIRD\u27s regulatory compliance approach
Resource assessment report no. 3: Gascoyne Demersal Scalefish Resource 2024 assessment
The Gascoyne Demersal Scalefish Resource (GDSR) comprises over 80 species inhabiting inshore (20-250 m deep) and offshore ( \u3e 250 m deep) waters in the Gascoyne Coast Bioregion (GCB; south of Onslow to north of Kalbarri). The GDSR is primarily targeted by commercial, charter and recreational boat-based line fishers. Snapper and Goldband Snapper are the indicator species selected for monitoring and assessing the status of the inshore suite of the GDSR, while Ruby Snapper and Greybanded Grouper are the indicators for the offshore suite.
Periodic assessments of GDSR indicator species demonstrated that historical fishing of Snapper led to stocks being below the limit reference level between 2010 and 2020. A formal harvest strategy was introduced in 2017 for the GDSR followed by a recovery plan for oceanic Snapper in 2018. The recovery plan is designed to limit total removals (including retained catches and estimated post-release mortality) of Snapper by all sectors to no more than 100 t and recover stocks to the threshold level by 2027 and the target level by 2037. The main commercial fishery targeting the GDSR, the Gascoyne Demersal Scalefish Managed Fishery (GDSMF), holds a Wildlife Trade Organisation accreditation (valid until January 2028; Department of Climate Change, Energy, the Environment and Water 2025).
This 2024 GDSR assessment is focused on the two main indicators (Snapper and Goldband Snapper) that collectively make up are a large proportion of the total catches retained by all fishing sectors. The assessment includes available catch and effort information and biological data (sizes and ages) for Snapper up to 2023 (inclusive) and for Goldband Snapper up to 2020 (inclusive)
Fisheries Research Report No. 361: 2024 assessment of the status of the Elasmobranch Resource of Western Australia
This document provides the 2024 risk-based weight of evidence stock assessment for the elasmobranch (sharks and rays) resource of Western Australia (WA). Gummy (Mustelus antarcticus), dusky (Carcharhinus obscurus), whiskery (Furgaleus macki), and sandbar (C. plumbeus) sharks are the most commonly captured species (~80% of the elasmobranch catch) and have been selected as indicator species for the status of the temperate elasmobranch ‘suite’. However, over 100 elasmobranch species have been caught in commercial and/or recreational fisheries in WA and, with the increasing number of elasmobranch species being listed in national and international protection lists, species-specific scientific advice on stock status at the local level is needed for these species

Bulletin 4936: Guidelines to importing and keeping regulated animals in Western Australia
Note: Updated December 2025 for changes in declaration and permit conditions, and transfer of restricted keeping bird permit business to DPIRD.
Introduced, exotic or alien animals are species that have been brought to a country or location where they do not occur naturally. (Hereafter referred to as introduced species). Mammals, birds, reptiles, and amphibians that are introduced or relocated to new areas often cause problems to agriculture, the environment and the community. Problems occur when introduced species: damage agricultural crops displace and compete with native animals and plants carry disease or parasites damage property cause land degradation have a negative impact on pets.
Introduced species that are kept in captivity can escape or be liberated and successfully establish populations in the wild and become pests. The harm newly-established species cause is not always obvious at first and it may take many years for populations to increase and cause widespread impacts. However, once they do establish in the wild they are near impossible to eradicate and control.
It is primarily introduced species that are declared pests under the Biosecurity and Agriculture Management Act 2007 (Act), by the Minister for Agriculture and Food, Western Australia (WA).
Prohibited declared pests under the Act, require an import permit to enter WA.
The Biosecurity and Agriculture Management Regulations 2013 (regulations) specify keeping categories for declared pests to regulate the purposes for which they can be kept, and who (entities) can keep them for that purpose. A keeping permit is the administrative tool used to assign conditions for keeping a declared pest.https://library.dpird.wa.gov.au/bulletins/1296/thumbnail.jp

Ecological risk assessment for the Western Australian Cephalopod Resource
On 27 October 2023, the Department of Primary Industries and Regional Development (DPIRD, Department) convened an ecological risk assessment (ERA) of the fisheries that access the statewide Cephalopod Resource (Resource), which comprises a range of octopus, squid and cuttlefish species. This document contains the background information used to support the ERA risk scoring process, and a summary of the workshop discussions that were relevant to the risk scoring. The background information includes an overview of Western Australian commercial fisheries that access the Resource, focusing primarily on the Octopus Interim Managed Fishery (OIMF), Cockburn Sound Line and Pot Managed Fishery (CSLPMF), South Coast Line and Fish Trap Managed Fishery (SCLFTMF), and commercial open-access fisheries (OAF) in each bioregion. This report also includes information about statewide recreational and charter fisheries that access the Resource. The Department conducts ERAs as part of its Ecosystem Based Fisheries Management (EBFM) framework. Accordingly, the ERA considered the potential ecological impacts of harvesting of the Resource. This includes impacts of fishing on all relevant retained and bycatch (non-retained) species, endangered, threatened and protected species, aquatic habitats and the broader environment. Risk scores were determined during the ERA workshop, based on available scientific information and expert knowledge. The assessment conformed to the AS/NZS ISO 31000 risk management standard, and to the methodology adopted by the Department, which uses a consequence-likelihood analysis for estimating risk. A broad range of stakeholders were invited to participate in the ERA workshop, including representatives of the commercial, recreational, and charter fishing sectors, State and Commonwealth Government agencies, the conservation sector, universities, and DPIRD staff including fisheries managers, scientists, compliance officers and biosecurity personnel. Outcomes and scoring from the workshop are summarised in this document. Thirty-eight ecological components were scored for risk, including individual components that were separated by bioregion or by fishery. The vast majority (32) of ecological components were evaluated as low or negligible risks, which do not require any specific control measures. There were 6 medium risks, which were assessed as acceptable under the current monitoring regime and control measures that will be in place over the next five years. No components were scored as high or severe risks. It is recommended that the risks be reviewed in five years
