Abstract: Interim Biogeographic Regionalisation for Australia (IBRA) version 7.0 represents a landscape based approach to classifying the land surface of Australia. 89 biogeographic regions and 419 sub regions have been delineated, each reflecting a unifying set of major environmental influences which shape the occurrence of flora and fauna and their interaction with the physical environment across Australia and its external territories (excluding Antarctica). IBRA Version 7.0 data consists of two datasets. IBRA bioregions, which is a larger scale regional classification of homogenous ecosystems, and sub regions, which are more localised. IBRA Version 7.0 is the result of both significant changes to certain IBRA 6.1 boundaries, plus refinement of other boundaries due to better data availability amongst some states and territories, and alterations by the states/territories along state borders. The updated boundaries were jointly defined by the Commonwealth, State and Territory nature and conservation agencies. In this respect refinements were carried out to all mainland jurisdictions with significant changes in Queensland and South Australia. In addition the dataset was also updated to more closely conform to the Geoscience Australia 1:100K State borders, and a standard coding/naming convention introduced (for both regions and sub-regions) resulting in differences to both names and codes used in earlier IBRA Versions.
Various sources were used to delineate islands - these included the GA100K Admin layer plus the Australian Maritime Boundaries dataset, a Coral Sea dataset (held in ERIN) and the GA Commonwealth Fisheries 2006 dataset.

Data Quality Information:

Scope of quality information: dataset

Lineage:
States and Territories provided the base data for inclusion in IBRA Version 7 Auricht Projects then undertook spatial refinements of the boundaries to ensure that edgematching of boundaries were to the state borders and coastline. The Geoscience Australia 1:100,000 dataset was used to maintain this standard. Draft outputs were provided to State/Territory Agencies for cross-checking. Final checking of topology was undertaken by the Australian Government Department of Sustainability, Environment, Water, Population and Communities.

The functions of the former Department of Environment and Resource Management will now be delivered by the following departments: Department of Environment and Heritage Protection, Department of Natural Resources and Mines, Department of National Parks, Recreation, Sport and Racing, Department of Energy and Water Supply, Department of Science, Information Technology, Innovation and the Arts

Data quality report - Absolute external positional accuracy:
Less than two kilometres in most areas of Australia. Generally, the data is accurate to at least 1:250,000

Data quality report - Attribute accuracy:
The naming of regions is the responsibility of individual jurisdictions. The naming of those regions that cross state/territory boundaries is decided on agreement with those jurisdictions in question. The two IBRA datasets (bioregions and sub-regions) contain the following attributes:

REG_CODE_7 – Alphabetic identifier for the IBRA region; REG_NAME_7 - The full name of the IBRA region; AREA – Area in Metres; HECTARES – Area in Hectares; SQ_KM – Square Kilometres ; REC_ID – Numeric identifier for the IBRA region; REG_CODE_6 – Alphabetic identifier of the previous IBRA6.1 region; REG_NAME_6 - The full name of the previous IBRA6.1 region; REG_NO_61 – Numeric identifier of the previous IBRA6.1 region; STATE - Abbreviation of State or Territory

Data quality report - Conceptual consistency:
ERIN undertook a systematic process to ensure all spatial and non spatial data was correctly compiled. This included checking for label errors and also for removing over-shoots and under-shoots in relation to the state borders.

Data quality report - Completeness:
The data is complete for IBRA version 7. Further refinement will be carried out to improve border regions in time.
