Bureau of Meteorology Marine Forecast Zone boundaries for Australia. Forecasts for the areas delineated by these boundaries are issued by the Bureau of Meteorology on a routine basis. These zones include coastal, local and inland waters. This dataset replaces the Coastal Water Forecast Areas.

PurposeTo show the Marine Forecast Zone boundaries
The Marine Forecast Zones for coastal waters are based on areas documented in the Bureau of Meteorology Marine Weather pamphlets. The spatial data were created initially by buffering the Geoscience Australia 1:10,000,000 coastline (plus seven islands) by 60 nautical Miles (for the offshore limit) and -5 Nautical Miles (for the inland limit). The islands included were Melville (NT), Rimbija (NT), Fraser (Qld), Morton (Qld), Kangaroo (SA), King (Tas) and Flinders (Tas). Existing reference points were used to depict the ends of each zone and compass point angles were mainly used to define the areas from the -5nm to 60nm. Two Geoscience Australia coastlines (from Geoscience Australias GEODATA Coast 100K 2004 and the GEODATA 2.5 M 2003 products) were inserted to provide versions of the coastal waters with the Australian boundaries.
Subsequent changes to the boundaries was based on feedback from Port Meteorological Officers (PMO) duing 2004-2005. These changes mainly related to angles between zones and replacing curved lines with straight lines in Northern Australian and Bass Strait.
Label changes to Bass Strait zones occurred in November 2005.
In February 2007, the zone of "Israelite Bay to Eucla" was changed to "Israelite Bay to SA Border". In addition, the boundary between the coastal zone "East Coast" of Victoria and the "South" of NSW was moved to the easternmost point of Gabo Island.
In October 2008, the Victorian Coastal Water Zone of East Coast was split north-south at Lakes Entrance. The new zones were named Central Gippsland Coast and East Gippsland Coast.
In April 2009, Port Phillip, Western Port and Gippsland lakes were added. As these areas cannot be represented by a inland buffer of 5 nautical miles, only the coastline versions will be maintained.
Coastal waters for South Australia changed in October 2011 as part of the new forecasting system.
The local, inland and off shore areas were added to create a more comprehensive dataset of Marine Forecast Zones. The delineation of Moreton Bay Waters was based on GIS data from Maritime Safety Queensland.
Local waters in WA and NT are not currently defined.
In December 2011, the "Fraser Island Offshore Waters" changed to "Fraser Island Waters"
In October 2012, there were changes to WA districts with boundary changes occurring in the SE, Central and Northern regions. All WA districts were renamed. Two local waters, namely Perth and Melville Waters were added. Jurisdiction on WA-NT border was transferred to WA from NT. The attributes of AREA, PERIMETER, NAME_, NAME_ID and CW_NUM were deleted.
In October 2013, there were major changes for Queensland, including extending the zones in Torres Strait and different delineation of boundaries in Gulf of Carpentaria and along most of the east coast. The area defined as Moreton Bay was increased. Offshore areas were not included.
In October 2014, boundaries for Northern Territory changed to complete the upgrade of the forecasting system for the whole of Australia. In addition, field names were changed to to align more closely with those used in the NexGen system and the AMOC Area Code (AAC) was added for linkage to forecast products. The fields are AAC, DIST_NO, DIST_NAME, STATE_CODE, TYPE, PT_1_NAME and PT_2_NAME.
In July 2016, the Great Barrier Reef Offshore Areas was included.
In November 2016, the more detailed 1:100K coastline was replaced with the 1:2.5 M coastline with limited islands. This change ensures consistency of coastlines with other Bureau products.
