A methodology for local disaster management planning based on Australian/New Zealand Standard AS/NZS 4360:1995 — Risk Management has been developed as an out-working of a Flood Risk Study for Murweh Shire. The methodology has relevance to all local governments, particularly in view of National Disaster Relief Arrangements (NDRA) that now link the extent of NDRA funding available for a re-occurring natural disaster event to the existence of disaster mitigation actions or plans. This places a premium on actions being taken by local governments to mitigate public safety risk at community level.Learn more

Eildon Dam, Goulburn Weir and Waranga Basin in Victoria are owned and managed by Goulburn-Murray Water (G-MW). Eildon Dam and Goulburn Weir are situated on the Goulburn River, while Waranga Basin is an offstream storage supplied from Goulburn Weir.
In November 2004 a dam safety emergency exercise involving the establishment of a central Emergency Coordination Centre at Tatura as well as Emergency Operations Centres at each of these three dam sites was conducted. The exercise presented a variety of emergency situations in stepped time increments, including earthquake, mechanical failure, a hazardous material spill and a terrorism related incident. External agencies were not involved.
The exercise was part of an ongoing G-MW program designed to test and improve dam safety emergency planning and response systems for all of G-MW’s dams and highlighted areas where procedures, situational management and communications can be enhanced.
Outcomes aimed for in G-MW’s program are improvement in Dam Safety Emergency Plans and internal communications, together with clarification of roles, responsibilities and capabilities.Learn more
The valuable experiences learned from this dam safety emergency exercise and plans for a larger scale exercise involving other emergency management agencies will be shared with others through this paper.

Lessons learned from recent major incidents and related enquiries in Victoria in concert with the adoptionLearn more
of an all-emergencies all-communities philosophy have informed both the scope and reach of the current
emergency management and dam safety regulatory environment. Victorian dam owners now have a statutory
obligation to implement an all-emergencies all-communities approach to risk assessment at their assets and,
as part of that, to adopt this approach as part of their “business as usual” activities. A major outcome of
this requirement is that for major dams, risk management is now being driven from Board and senior
management level: the implementation of controls and actions is formalised. As a consequence, there is a
better understanding across the organisation of new and emerging risks that require new technologies,
thinking and expertise and an improved appreciation of asset interdependencies and the risk posed to reliant
stakeholders. With other reforms including oversight and audit arrangements in place, the move from “doing
enough” to striving for “good’ industry practice, aided by an improved regulatory regime and statutory
processes, is well established. A brief consideration of the lessons learned from the February 2017 Oroville
dam incident in this context concludes the paper.
