The authors developed a systems framework for analysis of integrated catchment management in the ACT region including downstream impacts on the Murray Darling Basin. This analysis supported the ACT government business case for integrated catchment management. The ACT government successfully submitted the business case to the Australian Federal government and the supporting analysis was positively reviewed as part of the process.

This study employed unique spatially and temporally explicit methods of systems analysis. It was found that alternative water cycle management embedded within existing centralised water cycle networks can offer technically, commercially and environmentally viable strategies.

The analysis was subject to detailed stakeholder and review processes. A hindcasting process was utilised to confirm the accuracy and enhance of the existing Systems Framework. The integrated systems model was used to support an evidence based policy process used by the Victorian Government. The enhanced systems model successfully reproduced the behaviour of regional storages, water demands and wastewater discharges. The spatial robustness of the systems model was verified for generation of water demands and wastewater discharges throughout Greater Melbourne. Costs and greenhouse gas emissions in the systems model were also successfully verified against all available data.

A recent conversation with Kim Stephens from the Partnership for Water Sustainability in BC has highlighted an eventful parallel journey between Canada and Australia towards a more sustainable and resilient society over the last decade. This conversation resulted in agreement to document reflections on the parallel journey. It has been a journey of different cultures and climates but similar challenges to ensure water supplies and enhance our environment whilst striving for greater inclusiveness throughout society. This first of three articles focuses on insights gained from interactions with Canadian leaders during the period 2001 to 2005.

The Senate of the Australian Parliament has initiated an inquiry into the stormwater resource in Australia. This submission responds to this important issue from the necessary context of the entire water cycle.

This submission discusses the key insights from initiation of water cycle reform and policy development for water cycle management in the jurisdictions of the New South Wales, Victorian and Australian Capital Territory governments.

Policies and strategies for stormwater management are needed in the context of water cycle and planning systems. It is essential to frame evidence based policy from the “bottom up” using all available data and integrating all available spatial and temporal scales of behaviour. New policy frameworks are required to integrate rainwater and stormwater harvesting, soil profiles, vegetation, land uses and waterways in town planning processes.

Longitudinal sampling from rainwater tanks and mains water throughout Australia was utilised to analyse the metal and elements in water supplies. A majority of analysed samples were compliant with Australian Drinking Water Guideline values for metal and elements, although 12% of samples exceeded guideline values for one or more element. However, repeated non-compliance with guidelines was rare.
