Presentation Outline1. Background to DERM and its role2. Background to water resources and water management in Queensland3. Concluding Remarks
About Queensland• Second largest state in Australia by area, covering 1.73 million km2• The third largest by population, with 4.4 million people• Fastest growing State with South East Queensland (SEQ) the fastest growing region• Over half the population is located in the south east of the state, which includes Brisbane• The majority of the remaining population live in towns located along the east coast• The Queensland economy relies heavily on exports from the mining (especially coal) and agriculture sectors and on tourism
Queensland’s Annual Rainfall• Queensland’s annual rainfall is generally within the range of 1000 to 1600 mm• The extremes vary from 200 mm/a in the south west to 3200 mm/a in the State’s Wet Tropics region• Generally, rainfall is highest near the coast and decreases further inland – highly variable
Queensland’s Runoff• Around 53 percent of the State’s total runoff of approx 160,000 GL/a (about 40% of Australia’s total) comes from catchments on the State’s east coast• 41 percent of runoff occurs in the sparsely populated catchments that drain to the Gulf of Carpentaria• 6% of the water in rivers drains to inland river systems and less than 5% occurs in the heavily populated SEQ region• Runoff from catchments on the north- east coast and in the Gulf is heavily associated with tropical cyclones – highly variable
Great Artesian Basin• Largest known artesian basin in the world;• Covers an area of more than 1.7 million square kilometres.• Stores 64.9 million GL of water.• Underlies more than 65% of QLD.• Currently, 1.5 GL/day is discharged from the basin.• Sole source of water for stock and domestic use in many areas.
Water Use in Queensland 5% Total average annual water consumption 2% 2% is about 4,500 GL/a 4% 10% Agriculture Household Water supply, sewerage and drainage services Manufacturing 11% Mining Electricity and gas 67% Other industries Source: ABS
Water in Queensland• Water supplies are drawn from a variety of sources: – Unsupplemented Surface Water; – Supplemented Surface Water; and – Groundwater.• Although proportions vary from area to area, each of these sources accounts for around 1/3 of total water use• Qld has 21 dams with a capacity exceeding 100 GL• These dams are owned by either the State Government (SunWater, SEQwater) or Local Governments• About 12,500 tradable water access entitlements have been granted with a total volume of about 4,055 GL and a value of over $4 billion
Queensland Departmentof Environment and Resources Management • In Qld, the Department of Environment and Resource Management (DERM) is the State Government’s lead agency for policy, legislation and programs relating to the planning and management of the State’s environment and natural resources, including water resources. • DERM works together with industry, community, landholders, Local Governments and other agencies with the aim that the management of water is efficient, effective, innovative, responsible and balanced, and sustainable. • State Governments are not accountable to the Commonwealth Government, although they receive significant funding from the Commonwealth and hence are subject to its influence. The exception is the Murray Darling Basin – States have given rights for setting sustainable diversion limits, environmental watering plans, water quality and salinity management plans, and water market rules back to the Commonwealth.
DERM’s Role: key areas of responsibility(Strategic Plan 2010-2014)• Delivering fit-for-purpose services to our clients• Meeting the challenge of climate change• Ecosystems are healthy, protected and bio-diverse• Managing Queensland’s land, water and vegetation resources responsibly• Protecting and enhancing the state’s natural environment and cultural heritage• Securing water for Queensland’s future

Water reform approach in Queensland Institutional to ensure to define Reformcommercial relationship viability of between damwater service Planning Reform owner, provision customer/water user and regulator to ensure certainty, security, transparency and confidence on planning outcomes/processes Pricing Entitlements Reform Reform to define ‘product’ and ‘price’- All underpinned by best available science and active stakeholder engagement
OutcomesIn the context of water, Queensland is focussed onachieving the following ‘outcomes’: • Healthy river and aquatic systems • Efficient and sustainable water use and management • Bulk water supply security • Safe drinking water quality • Asset reliability/infrastructure capability • Streamlined and effective regulation • Capable and skilled water industry • Resilient regional communities

Concluding Remarks• Sustainable water management and water supply security are still critically important issues in Queensland/Australia• Queensland has extensive experience and capability in achieving multiple outcomes for the water sector and is looking to further engage with other partners and parties in local and international water business• More information on Queensland Government activities from our Websites www.derm.qld.gov.au www.qwc.qld.gov.au www.water.qld.gov.au Thank you!
