The aim of the Tiered Response Structure is to provide suitable response resources at the right place at the right time, hence the resulting capability should:

  • Be commensurate with the assessed risk;
  • Encourage cooperation, mutual assistance and integration of shared resources;
  • Be fully scalable via a mechanism of escalation through the three tiers;
  • Be tested, maintained and verified as part of a defined preparedness framework; and
  • Employ the most appropriate response options reflecting a net environmental benefit analysis (NEBA).


  • Tier 1 - Packages
  • Tier 2 - Packages and Centre Support
  • Tier 3 - Support
