This unit of competency involves the skills and knowledge required to perform a liaison role (a liaison person) between an organisation managing emergency response and/or recovery and another organisation providing services or assistance in those efforts. It involves establishing the purpose and priorities of the managing and supporting organisations, the amount of decision-making authority delegated (if any), and communication channels and reporting requirements. The liaison person represents their agency to support the coordination of assistance between the managing and supporting organisations. Based on a request for a liaison person being made and accepted, a liaison person may be sent from a support organisation to the managing organisation, or vice versa. As such, either may be the sending or receiving organisation. The unit applies to personnel involved in emergency response and/or recovery within or by emergency service organisations, government agencies, private sector businesses, critical infrastructure owners and operators, community groups, not for profit organisations and community event committees.
