Introduction 1.1 Purpose of this Document Kimberley Technology Solutions Pty Ltd (KTS) is referring the Cockatoo Island Multi-User Supply Base (the Proposal) to the Department of the Environment and Energy (DotEE) under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The purpose of this document is to summarise the Matters of National Environmental Significance (MNES) that may be impacted by the Proposal, including an assessment of the significance of any potential impacts using the Significant Impact Guidelines 1.1 Matters of National Environmental Significance (DotE 2013). ‐ 1.2 Overview of the Proposal KTS proposes to construct and operate the Proposal from Cockatoo Island. The Proposal would establish a hi-tech / subsea focused supply base as part of a multi-user supply chain cluster. Developments would comprise an upgraded airfield, a wharf and an aftermarket subsea workshop as well as other related support infrastructure. The Proposal would support the exploration, development and operation of oil and gas projects in the Browse Basin. It will also increase opportunities for other strategic industries such as Defence and Tourism in north-western Australia and significantly reduce the operating costs of the mine on Cockatoo Island. The Proposal represents an opportunity to use the Norwegian model as a test case in Western Australia which, when established, will draw business from existing locations in Asia and interstate. It can be used by the State Government as a catalyst for bringing real economic development to the Kimberley region. 1.3 The Proponent The Proponent for the Proposal is Kimberley Technology Solutions Pty Ltd, a joint venture between NorSea Group, Brunel Australia and Advantec Group and advised by Global Air and Energy (Singapore). Contact details for the Proponent are: Mr Jeremy Bower Kimberley Technology Solutions Pty Ltd Level 2, 101 St Georges Terrace, Perth WA 6000 Ph: 08 9429 5600 ACN: 615 631 386 1.4 Location of the Project Cockatoo Island is located approximately 7 km off the Western Australian coast within the Buccaneer Archipelago, approximately 130 km north of Derby (Figure 1-1). The island is located within Yampi Sound, between Irvine and Koolan Islands. The island has historically been mined for iron ore, with mining operations on the island commencing in 1951. Mining operations on the island are currently in care and maintenance. Existing infrastructure and disturbances on the island include an airstrip, processing plant, open pit mine (involving mining of high grade ore from a deposit below sea level), a permanent seawall, wharf with ship loading facilities and historic township.
