The information contained within these tables has been derived from Certified Plans and other sources and is accurate for most applications. It should be noted that some points are difficult to describe using coordinates alone and if 100% accuracy is required navigators should refer to the Certified Plans. Certified Plans for the Marine National Park system are available from the DEPI website ( www.depi.vic.gov.au ) which describe the legal boundaries of the reserves. July 2013 Marine National Parks and Marine Sanctuaries Boundary Coordinates WGS84 – Degrees, Minutes & Seconds Only use the coordinates if your GPS Receiver is in WGS84 Datum and the coordinate system is Latitude/Longitude – Degrees, Minutes &Seconds (i.e. DDD°MM’SS’’) . If you are plotting these points on a Nautical Chart, remember to check that the datum of the chart is the World Geodetic System . This will be found near the Chart Title . If the chart is not WGS84, you will need to refer to a different list of coordinates.

    VWSG BULLETIN JOURNAL OF THE VICTORIAN WADER STUDY GROUP Number 40 August 2017 ISSN 0159-6896 VICTORIAN WADER STUDY GROUP INC. MISSION STATEMENT The principal aim of the Victorian Wader Study Group is to gather, through extensive planned fieldwork programs, comprehensive data on waders and terns throughout Victoria on a long-term basis. This scientifically collected information is intended to form a factual base for conservation considerations, to be a source of information for education of a wider audience, to be a means of generating interest of the general community in environmental and conservation issues, and to be a major contribution to the East-Asian Australasian Flyway and Worldwide knowledge of waders and terns. FORMATION/BACKGROUND The wader banding fieldwork, which led to the formation of the Victorian Wader Study Group, commenced in December 1975. The Group was formally named in late 1978 and incorporated in 1986. 2 VICTORIAN WADER STUDY GROUP INC.
