Mandatory Transition to Resources Online Portal for WA Environmental Approvals
The Western Australian Department of Mines, Petroleum and Exploration (DMPE) announced on 14 April 2026 that its legacy Environmental Assessment and Regulatory System (EARS) will be permanently retired and replaced by a new consolidated digital platform called Resources Online. From 9 June 2026, use of Resources Online will be mandatory for the lodgement of Environment Plans (EP), Oil Spill Contingency Plans (OSCP), and Native Vegetation Clearing Permits (NVCP) under the Mining Act 1978 (WA) and State petroleum legislation. This is not a voluntary upgrade or a parallel-running trial period. It is a hard cutover with a defined blackout window, and the consequences of missing it will fall directly on project timelines and client approvals.
For environmental consultants, project managers, and proponents active in Western Australia’s resources sector, this transition represents one of the more operationally significant administrative changes to hit the approvals process in recent years. The shift affects three of the most commonly lodged regulatory instruments in WA mining and petroleum project delivery. Environment Plans govern how proponents manage environmental risk across the life of a project. Oil Spill Contingency Plans are a mandatory requirement for offshore and onshore petroleum operations. Native Vegetation Clearing Permits, administered under Part V of the Environmental Protection Act 1986 (WA), are routinely required for project footprint establishment and infrastructure corridors. All three instruments will move exclusively to the new platform on the same date.
The announcement also signals a broader digital transformation agenda within the DMPE. Resources Online is intended to consolidate what has historically been a fragmented lodgement environment across multiple portals into a single-user interface. While the long-term efficiency benefits of that consolidation are clear, the transition period itself introduces real compliance risk for practitioners who are not actively managing their submission pipelines against the June 2026 deadline.
Resources Online Transition Timeline and Blackout Periods
The timeline for the EARS retirement contains three distinct phases that practitioners must understand separately. The first is the operational deadline for the existing legacy portals: both the EARS Online portal and the Departmental Submissions portal will permanently stop accepting applications for EPs, OSCPs, and NVCPs on 4 June 2026. That date is the last day a submission can be made through the current systems. The second phase is a system blackout running from 5 June 2026 through to 8 June 2026 inclusive, during which no online submissions can be made through any portal for these instrument types. The third phase is the mandatory commencement of Resources Online from 9 June 2026, at which point all new submissions must be lodged through the new platform.
The four-day blackout window between 5 and 8 June is the most operationally sensitive element of this transition. Any EP, OSCP, or NVCP that is not lodged by close of business on 4 June 2026 will not be submittable until 9 June at the earliest. For projects with tight regulatory timeframes, statutory decision-making clocks, or contractual milestones tied to approval dates, this gap is not trivial. Native Vegetation Clearing Permits in particular can be time-critical instruments where delays of even a few days cascade into significant construction programme disruptions. Consultants advising proponents on clearing timelines for the second quarter of 2026 must factor this window into their programme planning now.
The DMPE has confirmed it is actively seeking industry participants to join user testing sessions for Resources Online scheduled throughout May 2026. This is a meaningful opportunity that should not be treated as optional. Participating in pre-launch testing allows practitioners to identify interface issues, understand document formatting requirements, and test submission workflows before the mandatory start date. The risk of not engaging with May testing sessions is straightforward: consultants who attempt their first Resources Online submission on or after 9 June without prior familiarity with the platform face a materially higher probability of administrative errors, formatting rejections, or incomplete lodgements during what may be a high-pressure phase of project delivery.
The regulatory instruments affected span two pieces of Western Australian legislation. Environment Plans and Oil Spill Contingency Plans fall under the Mining Act 1978 (WA) and State petroleum legislation, including the Petroleum and Geothermal Energy Resources Act 1967 (WA) and associated regulations. Native Vegetation Clearing Permits are administered under Part V of the Environmental Protection Act 1986 (WA), with the Environmental Protection (Clearing of Native Vegetation) Regulations 2004 (WA) governing the assessment criteria and conditions. This means the transition affects not just mining project teams, but also petroleum operators, environmental approvals managers, and specialist clearing permit practitioners who may operate across both legislative frameworks.
Regulatory Context: WA Resources Approvals Reform
Western Australia’s resources sector operates under one of the most complex environmental approvals frameworks in the country. The DMPE administers environmental management requirements under the Mining Act 1978 (WA), while the Environmental Protection Authority (EPA WA) retains oversight of significant project-level environmental impact assessment under the Environmental Protection Act 1986 (WA). Native vegetation clearing sits at the intersection of both agencies, with Part V clearing permit applications assessed by the Department of Water and Environmental Regulation (DWER).
