Seismic surveys undertaken by the petroleum industry and the energy sector in offshore waters use high intensity airguns to characterise seabed petroleum resources and/or potential offshore energy installations. Seismic noise has been shown elsewhere to have adverse effects on marine biota including direct (e.g. injury) or indirect (e.g. behavioural) impacts. A review of relevant literature (including unpublished studies conducted in Victorian waters) is required to fully evaluate potential consequences of expanded seismic surveys. Such a review will provide a more robust basis for decision making by authorised planners consistent with a precautionary approach to development.

Sectors in the blue economy need to understand and manage social expectations in order to maintain their social license and ensure a satisfactory triple bottom line. This is a particular challenge for emerging industries, where data relating to community attitudes and expectations is limited. In the case of Tasmanian seaweed aquaculture, securing social license may be further complicated by existing perceptions and conflict surrounding salmon aquaculture.
The key elements needed to address the challenge of establishing and maintaining a social license for seaweed aquaculture in Tasmania are:
1. A survey of current community attitudes to industry expansion.
2. A tool to understand the evolution of attitudes and test communication strategies, policy options and industry practices in relation to managing social risk.
3. A coherent set of strategies for navigating pathways towards a social licence for seaweed aquaculture.
