Response Management Structure

Most incidents are managed effectively by the RMA Incident Controller and the IMT. As an incident grows in size and complexity so too does the need for sharing information, coordinating resources and exercising oversight. There may be a requirement for regional and state level arrangements to be activated for managing and coordinating resources, consequences and public information across the region or state.

In Tasmania, there are three levels of response arrangements: Municipal, Regional and State. In addition, there are existing arrangements for National crisis coordination. Click to reveal the pathway:

Local to National Coordination Pathway

Maintains overview of State’s commitments and potential external resource requirements.

  • Maintains state-wide overview of various agencies’ commitments and potential for external resourcing if required
  • Assists regional and local level response by coordinating resources (including external resourcing if required)
  • Overseeing consequence management and early recovery planning.

Maintains overview of the activities, resources and consequence management of incident/s occurring within the region.

Owner/Manager or RMA responsible for managing activities at the incident site and resolving the incident.

Response Management Authorities (RMA)

Management Authorities provide direction so that capability is maintained for identified hazards or emergency events across the PPRR phases. Management Authorities are responsible for coordinating and providing guidance for comprehensive emergency management. Management Authorities’ activities can range from providing advice (as required) to actively coordinating and aligning effort between relevant emergency management partners.

The RMA is the agency in control of the specific response actions are aligned with internal operational doctrine and pre-planned arrangements described in relevant emergency plans at municipal, regional and state levels.

The role of a Support Agency

Support Agencies are organisations responsible for the delivery and/or coordination of specific functions, as agreed with Management Authorities. Support Agencies command their own resources in collaboration with the Management Authority, as required.

The role of Support Agencies may include:

  • Providing functional support for activities across the PPRR phases. This can include providing workers, goods and services, especially for operations
  • Providing advice relating to activities across the PPRR phases
  • Requesting assistance from and coordinating efforts with other Support Agencies and other organisations to maximise use of all available resources
  • Identifying ways to improve the emergency management capacity of the agency.


The management of Information Flows is a key incident management function and processes must be in place to communicate  across an organisation involved, upwards to the delegating authority and government, and out to the community and general public is depicted in the flow chart, adapted from the AIIMS 2017 Manual. The areas of the flow chart are :

  • UP- reporting up within agencies/government
  • OUT-to community and general public
  • ACROSS-reporting to other organsiations involved
  • WITHIN-regular exchange of information up and down the incident management structure.
