Australian Partners


The Water and Environment Group of BMT is one of Australia’s premier environmental consultants. Our staff include engineers, environmental scientists, ecologists and environmental planners and are supported by an in-house team of GIS technicians as well as a specialist marine and aquatic field data and survey unit. The firm’s head office is in Brisbane and has branch offices located in Newcastle, Sydney, and Melbourne.

BMT has the in-house skills to provide an integrated engineering, ecological and scientific service to our clients. The diversity and strength of our staff enables us to provide innovative and practical solutions, supported by comprehensive field data capability and sophisticated numerical modelling.

We are recognised for our award winning work in climate change adaptation, water quality management and planning and water efficiency. We have authored and co-authored several industry-accredited guidelines and policy documents at the local, state and national levels and regularly provide capacity building (e.g. training workshops).

BMT specialises in:
• Environmental impact assessments
• Hydrology and flood hydraulics
• Environmental water quality and quantity
• Aquatic ecology and ecosystem services
• Floodplain management/ Flood intelligence
• Development approvals and environmental management
• Coastal processes and management
• Integrated total water cycle management
• Field data capture
• Software development and web data provision

  • Pangia Water Supply Project, Papua New Guinea (2014)
    The Pangia water supply project was designed to provide safe and reliable potable, reticulated water to the rural township of Pangia (Southern Highlands Province, PNG). BMT was commissioned to prepare a baseline environmental study for the project, covering the physical, biological, socio-economic and cultural environment, and to submit all necessary documentation to obtain environmental approvals for the activity. Habitat mapping, identification of environmental values and water quality characterisation, including sample collection, were undertaken during BMT WBM’s site visit. Household surveys were distributed during the site visit to further understand the community’s water resource use and willingness to pay for a reticulated water supply. The study also included an analysis of environmental impacts and an Environment Management Plan
  • Environmental Flows Technical Study , Papua New Guinea (2012-2013)
    Surface water extraction was planned from three local creeks for water supply purposes. BMT was engaged to conduct an environmental flow assessment to determine whether proposed activities were likely to cause environmental harm to aquatic species and/or environments), and if necessary, to propose changes to better reflect actual operational conditions and ecological constraints. BMT WBM undertook aquatic sampling, determined the flow regime components that maintain aquatic ecosystem functions, and identified the linkages between these flow components and the aquatic habitats and species. Preliminary environmental flow objectives and a set of numerical hydrological criteria were developed, which provided a basis for evaluating whether extraction could impact on the ‘most susceptible aquatic organism’ and aquatic habitats more generally. Hydrological modelling was undertaken for study area waterways to determine likely changes to the flow regime. Based on modelling results, recommendations were made regarding modification of the definition of ‘base flows’ in the Water Extraction Permit. This proposed modification ensured the overall management intent of minimising harm to aquatic ecosystems was maintained.
  • Hela Hydropower Project, Papua New Guinea (2013-2014)
    The BMT team was commissioned to conduct all environmental and socio-cultural studies and assessments necessary to accompany an Environment Permit application for the development of a hydropower project on the Tagari River, near the Hewaii Falls in Hela Province, PNG. The project, to be funded under international financing guidelines, required studies to understand local terrestrial and aquatic biodiversity, hydrology, and socio-cultural conditions. Hydrologic and hydraulic impacts from water diversion were a key focus of both the environmental and social impacts.
  • Choiseul Bay Climate Change Adaptation Plan, Solomon Islands
    BMT led a project team, on behalf of AusAID to develop a climate change adaptation plan for Taro Island, the provincial capital of Choiseul, Solomon Islands. The project involved detailed field surveys, wave and tsunami numerical modelling and extensive community consultation. A detailed plan was developed that included preparation of an entire new town planning scheme. The recommendation of the project was the planned relocation of the Taro Island population to a new town site on the adjacent mainland. This project won 3 Qld PIA state awards and a national PIA award. It has also had extensive media coverage
  • Kakadu National Coastal Vulnerability Assessment, Australia (2008–2010)
    BMT was commissioned to undertake an assessment of climate change impacts on river system dynamics, resulting environmental, social and cultural impacts in the Kakadu National Park and implications for government planning, management and policy responses. For more information –
  • Riverine Social Impact Assessment, Papua New Guinea (2011–2013)
    A review of existing information and preliminary flood modelling as part of a social impact assessment to investigate the village-scale impacts caused by flooding and land inundation from mine-derived sediments from the Ok Tedi mine in Western Province, PNG.
