Introduction Project Sea Dragon Pty Ltd, a wholly owned subsidiary of Seafarms Group Limited (Seafarms) (ASX: SFG), proposes to develop Project Sea Dragon, a large, fully integrated, prawn aquaculture project located in northern Australia (Notice of Intent, July 2015). The Notice of Intent (July 2015) was for construction and operation of Stage 1 of Project Sea Dragon at the Grow-out Facility to be situated on Legune Station. Legune Station is located in the north- western Northern Territory. The Stage 1 Legune Grow-out Facility will comprise approximately 1,080 ha of prawn farming capacity, plus associated infrastructure onsite. As part of the Environmental Assessment process, there was a requirement for the proponent to assess the actual and potential biting insect problems at the development site, to determine the potential for workers to be affected by pest and potential mosquito borne disease problems. Legune Station contains
