The Office of Groundwater Impact Assessment (OGIA) is an independent office responsible for assessing impacts from resource development in Queensland, including coal seam gas (CSG), conventional oil and gas, and mining; and then developing and supporting proactive strategies for managing those impacts.
OGIA is not a regulator. It is uniquely positioned to bring together the science and resource management. Its work is primarily focused on scientific investigation, modelling and monitoring relating to groundwater impacts, and support of an adaptive management framework for managing the impacts within cumulative management areas (CMAs) in Queensland.
The Department of Regional Development, Manufacturing and Water provides corporate and administrative support to OGIA. The work undertaken by OGIA is provided to the Department of Environment, Science and Innovation, which is responsible for regulatory compliance of groundwater management strategies and actions identified by OGIA. This includes statutory obligations on individual tenure holders for the proactive ‘make good’ of impacts on water supply, mitigation measures for impacts on groundwater-dependent ecosystems and installation of monitoring networks.
News and events
Review of CSG-induced subsidence
In late 2023, the GasFields Commission Queensland (GFCQ) undertook a review of the regulatory framework for CSG-induced subsidence. That review resulted in a number of recommendations being made to government. The Department of Resources has accepted the GFCQ’s review and announced that it will support six of the eight recommendations in full and two in principle. Several actions will be undertaken to address these recommendations, including:
- developing a new framework to assess, manage and compensate for CSG-induced subsidence impacts to farming operations
- expanding the remit of OGIA to provide advice on subsidence and develop tools to assess the impacts of subsidence on farming operations.

Annual review 2023 for the Surat UWIR
In January 2024, OGIA published the Annual review 2023 for the Surat UWIR (PDF, 1.9MB), providing an update on changes to circumstances that may materially affect the impact predictions reported in the UWIR 2021.
New journal papers published
In May 2024, scientists from OGIA published two journal papers:
- Subsidence associated with dewatering and gas extraction from coal seams: Contribution of desorption-induced coal shrinkage, published in the Journal of Hydrology
- A novel methodology for assessing the potential for formation bridging in coal seam gas fields: A case study from southern Queensland, published in Gas Science and Engineering

Aerial groundwater survey of the Condamine Alluvium
In May 2023, OGIA conducted an airborne electromagnetic (AEM) survey of the western Condamine Alluvium, between Dalby and Cecil Plains.
OGIA commissioned SkyTEM Australia to complete the survey, which took around one week to complete. The purpose of the helicopter survey was to improve understanding groundwater connectivity.
