South32 Worsley AluminaProposed Mining Expansion
Public Environmental Review (closes 29 August)
Have your say to protect our Jarrah Forest
This page will continue to be updated during the PER period. Please check back regularly.
South32 Worsley Alumina has released its Public Environmental Review (PER) documents seeking approval to clear 4,399 hectares of native vegetation (including Jarrah Forest) to expand its bauxite mining operations near Boddington and their alumina refinery near Collie. The proposed expansion will have serious direct and cumulative social, economic and ecological impacts, which are highlighted in the recent report ‘A Thousand Cuts – Mining in the Northern Jarrah Forest’.
This proposal comes at a time when according to the newly released State of the Environment Report 2022, the state and trend of the environment of Australia are poor and deteriorating as a result of increasing pressures from climate change, habitat loss, invasive species, pollution and resource extraction. Multiple pressures are creating cumulative impacts that amplify threats to our environment, and abrupt changes in ecological systems have been recorded in the past 5 years.

Values of the Jarrah forest
Our northern Jarrah Forest and the waterways within it are important for a multitude of reasons. The waterways of the Peel-Harvey catchment are environmentally, culturally as well as socially significant. The forest lies within the southwest biodiversity hotspot which forms one of 36 global biodiversity hotspots, where exceptional concentrations of endemic species are undergoing exceptional loss of habitat. Flora and fauna of the region is internationally renowned as one of the richest in the world. Within the Hotham-Williams subsystem alone, there are 31 threatened fauna species, including the State’s fauna emblem, the Numbat. The forests are critical habitats for a range of threatened species, including mainland quokkas and all three species of black cockatoo.
Along with its conservation values, the Jarrah Forest has long been highly valued by the Noongar people, then European settlers. It supports water and wood production, recreation, community well-being, acts as major carbon storage for climate mitigation, and contains significant ecological linkages.The area is increasingly popular for nature based tourism, with major walk and mountain bike trails such as the Bibbulman Track and Munda Biddi and areas like Jarrahdale and Dwellingup being popular tourist destinations for swimming, mountain biking, climbing, camping and bushwalking. It has a long history of timber harvesting and intensive mining for minerals such as bauxite, gold and tin. The 2021 announcement that native forest timber harvesting will end in WA by 2024 is recognition of the many other values of these forests.
Large areas of the northern Jarrah Forest and wheatbelt bioregions have been, and continue to be at risk from vegetation clearing, invasive species, disease, climate change including reduced rainfall, increased fire intensity and frequency and other threatening processes, which in turn affect environmental, economic and social well-being/health. In this context, many landholders, community groups, industry and government partners are working to protect and restore native vegetation within areas under their control. In the Peel-Harvey Catchment, this work is undermined by the extent of clearing and decline in vegetation condition.
Across all landscapes, native vegetation is changing due to the impacts of reduced rainfall, hotter than average and extreme temperatures, and increased burning. Bauxite mining in particular is well documented/known to have significant environmental impacts. In the northern Jarrah Forest and western wheatbelt, past, present and proposed large scale bauxite mining is one of the highest impact threats, through direct and cumulative impacts. Clearing for mining changes the structure, health and composition of forest ecosystems, can change water cycling and flow regimes, result in loss of carbon stores and change fire regimes.
Globally, Australia has amongst the highest rates of land clearing, with 29 mammals driven to extinction since European colonisation and more than 1,700 others being listed as threatened or endangered. Western Australia has had the third highest area of land cleared (between 2010 and 2018) with a total of 288,400 hectares cleared, of which 68,700 hectares were primary forests at least 30 years old. Recent data has shown clearing of native vegetation is occurring at a faster rate than is being replanted or regenerating naturally, including high quality habitat that is rich in biodiversity and important structural elements. While restoration and revegetation are important, recent reviews of natural resource management programs have highlighted the expense and difficulty of restoring habitat to a complexity and structure that resembles intact native vegetation. Mature forest, is very difficult or impossible to restore to its original state and is significantly more expensive than protection, as such conservation of forest areas with compatible uses such as nature based recreation should be prioritised over clearing and rehabilitation.
Background to Mining in the Northern Jarrah Forest
Bauxite mining has been operating in the northern Jarrah Forest since the 1980s, with South32 Worsley Alumina currently operating out of their mine near Boddington and Alcoa in Myara North and Holyoake areas . The Boddington Bauxite Mine is located to the central east of the northern Jarrah Forest subregion in the drier zone of the Jarrah Forest bioregion. Since operations began in 1984, Worsley Alumina has progressively cleared approximately 5,900 hectares of land and progressively rehabilitated approximately 3,200 hectares, of these areas.
Both companies have published intention to significantly expand their current mine and alumina production areas. South32 Worsley Alumina’s expansion includes 4,399 ha of vegetation clearing and Alcoa’s plans for the Huntly Bauxite Mine and Pinjarra Alumina Refinery include 6,621 ha of additional clearing. Both are being assessed under the Western Australian Environmental Protection Act 1986 and the Federal Environmental Protection Biodiversity Conservation Act 1999. The WA Environmental Protection Authority (EPA) has set that each company’s Environmental Review Document (ERD) is subject to an eight week Public Environmental Review (PER). The ERD is to inform the public, support the WA EPA’s and Department of Agriculture, Water and the Environment’s (DAWE’s) assessments (Commonwealth Department), and provide other decision-making authorities with a detailed review of the project and its potential environmental impacts.
WA’s peak environment and forest conservation groups have published A Thousand Cuts: Mining in the Northern Jarrah Forests to provide information and
analysis regarding the impacts of bauxite mining in the Northern Jarrah Forests. You can download the report here.
What’s being proposed
South32 Worsley Alumina are proposing to clear 4,399 hectares of native vegetation within their Primary Assessment Area (PAA), which equates to approximately 34 per cent of the remnant vegetation within the PPA. The project will directly impact flora and vegetation through clearing of land for mining operations and supporting infrastructure. Worsley’s ERD is based around 14 key environmental factors which are those parts of the environment that may be impacted by an aspect of a project, these include flora and vegetation, water, air quality and social impacts. Nationally conservation significant species that will be impacted include Black Cockatoos (Baudin’s, Red Tailed Black & Carnaby’s), Peregrine Falcon, Blue-billed Duck, Numbat, Woylie, Chuditch, Western False Pipistrelle, Rakali, Quenda, Western Brush Wallaby, Red Tailed Phascogale, Brush-tailed Phascogale, Western Ringtail Possum, Quokka and Dell’s Skink.
Why is it important to have your say?
How does the proposal impact you and why is it important to have your say?
It is clear that the proposal has the potential to significantly impact the forest and waterways, but whether you live locally, within the region, or further away, or even interstate or internationally, in what ways will clearing a further 4,399 hectares of native forest impact you? PHCC’s overarching concerns of the proposal area are:
- The PPA falls entirely within the Peel-Harvey Catchment, from the Hotham, Williams and Harvey Rivers sub catchments to the Peel estuary, as such has capacity to have major region-wide detrimental region-wide impacts.
- Cumulative impacts from historical and current activities, including those from other operations are insufficiently and poorly considered.
- Social implications including those to human health from dust, noise and air pollution, loss of productive agricultural lands, loss of amenity and ownership of land in the mine buffer and offset areas, impacts including loss of walk trails and recreation opportunities, damage to tourism experience and branding.
- Impacts to major regional ecological linkages.
- Loss of flows and contamination risk to downstream water sources including the internationally important Peel-Harvey Ramsar site.
- Ineffective and non-localised offsets for specific Matters of National Environmental Significance (MNES) for terrestrial fauna species.
- Rehabilitation program for disturbed areas since operations commenced in the 1980s but no areas from Bauxite mining have yet been handed back to the State.
- Loss of major carbon storage that would contribute to atmospheric carbon and climate change impacts as well as loss of climate change resilience and migration pathways.
- The latest scientific evidence establishes that we cannot tackle climate change successfully without tackling biodiversity loss together (https://ipbes.net/biodiversity-climate change). Key global to local issues are climate change and biodiversity loss. Prevention of the loss of biodiversity is critical to addressing climate change.
- Insufficient avoidance or protection of high environmental value areas.
- Impacts to water quantity and quality, including reduced stream flows, groundwater, availability of drinking water, freshwater inflows, in the context of already 20% reduction in flows in southwest Western Australia.
- There is little publicly available knowledge about the condition and trends of this bioregion within the Catchment.
- Local and regional activities such as this has global implications.
Impacts and specific concerns are outlined in the table in the section below that addresses Worsley’s key factors.
Because of this, PHCC encourages anyone with an interest to have a voice and participate in the public review by making a submission by 29 August 2022.

PHCC’s position statement
Peel-Harvey Catchment Council (PHCC) has serious concerns about the proposed expansion, from local and regional scale impacts and direct and cumulative social, economic and ecological impacts. You can read the position statement here.
A key focus of PHCC is to address the cause of actions which may have a negative impact throughout the catchment, to make evidence-based decisions for positive social and environmental change. We also aim to ensure our actions and submissions align with ours and our stakeholders responsibility to meets national and international obligations for biodiversity and climate change, from local to global issues.
PHCC is a community based, Natural Resource Management (NRM) regional body working across the Peel-Harvey Catchment, covering over 1.1 million hectares of the Serpentine, Murray, Hotham, Williams and Harvey River catchments. PHCC promotes an integrated approach to catchment management and the way we protect and restore the environment within the Peel-Harvey catchment guided by our vision of “People Working Together for a Healthy Environment”.
With funding provided through the Australian Government’s National Landcare Program, PHCC’s current projects support a suite of activities and actions that closely align with the Peel-Harvey NRM Strategy – Bindjareb Boodja Landscapes 2025 and the Australian Government’s Threatened Species Recovery Plans and Conservation Advice. PHCC is working with the community, landholders and other relevant stakeholders to improve the status of native vegetation and the trajectory of a range of threatened species, including threatened Black Cockatoos across the Catchment and. The protection and management of native vegetation is a key objective of natural resource management and the achievement of the Goals of our Regional NRM Strategy.
With the above approaches in mind the PHCC is preparing an evidence and value based submission on South32 Worlsey Alumina’s expansion proposal. Throughout the process we will be encouraging people to have their say, providing updates and release the draft submission before the 8 week review period closes.
