Abstract
This point data set was created to identify locations on (or near) the Australian coastline which were considered to represent significant changes in key environmental attributes of the coast as they pertain to sediment movement in the coastal zone. This data was created during and subsequent to the technical workshop hosted by Geoscience Australia in Canberra from 16-18 October 2012. This workshop brought together the team of Australian coastal science experts listed below. - Prof. Bruce Thom - University of Sydney and the Wentworth Group - Prof. Andy Short - University of Sydney - Prof. Colin Woodroffe - University of Wollongong - Dr. Ian Eliot - University of Western Australia - Mr. Chris Sharples - University of Tasmania - Dr. Brendan Brooke - Geoscience Australia - Dr. Scott Nichol - Geoscience Australia The technical workshop had the goal of creating regional (primary) and sub-regional (secondary) scale coastal sediment compartments - spatial zones (represented by polygons) within (or between) which sediment movement could be considered on scales and timeframes relevant to coastal management. The first step in this process involved the expert panel identifying and defining boundary points along the Australian coastline, after which the expert panel assigned relevant environmental attributes to each point. Following the development of the boundary points data set, breaklines representing the coast-perpendicular compartment boundaries were generated by extending a line from the defined offshore bathymetric contour to the defined onshore elevation contour. In every case a compartment breakline extends seaward and landward of its boundary point.

Lineage
Following the technical workshop hosted by Geoscience Australia in Canberra from 16-18 October 2012 where boundary point data was identified on the coastline (smartline), the data set was reviewed internally at Geoscience Australia and sent out to the workshop participants for review of the location of the points and the attribution detailing the reasoning for the break between compartments. This review was completed for each of the States by two of the workshop attendees to ensure a higher level of consistency across the data set. Following review by the experts the edited data was: - merged back into a national data set - checked with regards to consistency of attribution of name and physical location of the point against Geoscience Australia's Gazetteer product (Gazetteer of Australia 2012 Release). This resulted in some points being relocated to align more closely with the Gazetteer.
