The Cadastral dataset is the spatial representation of property boundaries and descriptions in the Barcaldine, Charters Towers, Flinders, Longreach and Winton local government areas. It is a fundamental reference layer for spatial information systems in Queensland. This is a complete extract from the Digital Cadastral Database (DCDB). Updates to this cadastre in 2012 will be released on the following dates: January 15 and 29 - February 12 and 26 - March 11 and 25 - April 8 and 22 - May 6 and 20 - June 3 and 17 - July 1, 15 and 29 August 12 and 26 - September 9 and 23 - October 7 and 21 - November 4 and 18 - December 2, 16 and 30. In 2013 the 1st release date will be January 13.

World Political Boundaries. The world boundaries dataset is comprised of free data sources from around the web. Made with Natural Earth (http://www.naturalearthdata.com/). Contains the Admin 0 - Countries cultural layer.

This map shows public and private land tenure, including Aboriginal and Torres Strait Islander land for the whole of Australia at a scale of 1:4.7 million. The land tenure boundaries depicted on this map generally define broadly classified areas greater than 50 square kilometres. Aboriginal land areas between 0.1 and 100 square kilometres are shown more comprehensively by symbols. The information on this map is complemented by statistical tables giving the total area of the land tenure categories for each state and territory. Also available as GIS data.

A 3.30 minute movie that has the viewer flying around Australia to 6 release areas: Gippsland Basin, Money Shoal Basin, Bonaparte Basin, Canning Basin, Browse Basin and Carnarvon Basin. The movie also stops at each release area to view, in detail, the: International/State seafloor boundaries; oil and gas fields; release areas; Basin/sub-basin outlines. Topographic markers are also shown, where possible.

This internal-use-only dataset contains the latest available Administrative Boundaries data - Australian Bureau of Statistics (ABS) Australian Statistical Geography Standard (ASGS) Main Structure (Mesh Blocks and Statistical Areas) - from PSMA which is updated every 3 months. Data is open to general public and can be downloaded.

The purpose of this document, Procedures for Describing Maritime Boundaries, is to provide unambiguous descriptions which give a consistent framework for government departments and agencies involved in the marine area. They provide: - policy makers and negotiators with a broad understanding of the geospatial issues which need to be considered when defining maritime boundaries - geospatial professionals with technical advice on how to describe and map maritime boundaries unambiguously - all stakeholders with legally defensible boundaries that improve administration over Australia's offshore jurisdiction and minimise the potential for litigation. The document does not replace the need to seek appropriate legal and geospatial advice when determining and describing maritime boundaries.

A sequence of stranded coastal barriers in south-east South Australia preserves a record of sea-level variations over the past 800 ka. Huntley et al. (Quat. Sci. Rev. 12 (1993a) 1; Quat. Sci. Rev. 13 (1994a) 201) attempted to test thermoluminescence (TL) dating methods and found good agreement between quartz TL ages with independent ages for these dunes. We investigate the accuracy of the single-aliquot regenerative-dose (SAR) procedure (Radiat. Meas. 32 (2000) 57) over an extended age range of 0-250 ka, by comparing SAR-OSL ages determined on quartz extracts from these dunes with the existing chronology. We show that Robe II range is 60 ka, and that Robe III is 100 ka old. Not surprisingly, the OSL ages increase monotonically from the Robe II range to the West Naracoorte range. For the younger dunes (<240 ka), the SAR-OSL ages agree with the expected ages within 1 errors, whereas for the older dunes the SAR ages are consistent with independent ages within 2 error limits. We consider these results to be very promising, and lend support to the large number of quartz SAR-OSL ages being presented in the literature, where such comparisons with independent chronology are not usually possible.

A revolution is underway in the regulatory intensity of the marine jurisdiction and the technologies by which the jurisdiction is defined, navigated on and policed. This revolution if not properly managed has the capacity to undermine the technical and legal compact by which the most fundamental aspects of UNCLOS are managed - the maritime zones. The ready availability of high resolution coastal imagery and data, collected at high repeat cycles breaks the nexus between cartographic products and the baseline determination where its legal definition is the physical coastline. It is impractical to monitor, compute, distribute and archive the baseline of a highly dynamic coastline. In addition, the increasing establishment of spatially complex marine regulations creates an insatiable demand for more certainty in the determination of maritime zones. For instance, Australia administers over eighty separate regulatory zones through a dozen different agencies. States require a new method of characterising their baselines that is defensible in a precise digital world, and does not impose the costly and burdensome process of mapping a coastline in constant flux. The practical resolution is to adopt a fixed baseline compiled from the best available digital data at an epoch, then periodically updated it when considered appropriate. A fixed baseline is the answer to this problem which will bring with it certainty and repeatability via a method that recognises the costly and complex overhead of coastline characterisation. In this paper I will present a case for the adoption of a fixed baseline; illustrate the expensive impracticality of attempting to represent a fluid coastline to a world demanding certainty; how fixed baselines could form the basis of maritime zones; and finally demonstrate that adopting a fixed baseline is consistent with and desirable to International convention.
