The Postcode Boundaries dataset is the definitive set of postcodes developed by Australia Post and PSMA Australia. Postcodes are allocated to geographic areas to facilitate the efficient processing and delivery of mail to customers. The current four digit numeric postcode system was introduced in 1967 in association with the first mechanised mail processing centre in Australia. The government land administration agencies in each state and territory are responsible for gazetting locality names and boundary positions. Postcodes are only allocated to localities officially gazetted by land agencies. In the majority of circumstances, a postcode covers an area comprising of more than one locality. The decision as to whether a new postcode or an existing postcode is to be allocated to a locality is based on operational efficiency. Issues that underpin the decision are critically analysed; these include the configuration of the Australia Post network, transportation connections and delivery arrangements.
This dataset provides the definitive postcode dataset for the entire Queensland extent

The Postcode Boundaries dataset is the definitive set of postcodes developed by Australia Post and Geoscape Australia. It includes two data layers, postcode boundaries (polygon data) and postcode centroids (point data).
Postcodes are allocated to geographic areas to facilitate the efficient processing and delivery of mail to customers. The current four-digit numeric postcode system was introduced in 1967 in association with the first mechanised mail processing centre in Australia. The Postcode Boundaries in most cases are an aggregation of Geoscape’s Suburbs/Localities boundaries for each postcode.
The government land administration agencies in each state and territory are responsible for gazetting locality names and boundary positions. Postcodes are commonly allocated to localities officially gazetted by land agencies. In the majority of circumstances, a postcode covers an area comprising of more than one locality. The decision as to whether a new postcode or an existing postcode is to be allocated to a locality is based on operational efficiency. Issues that underpin the decision are critically analysed; these include the configuration of the Australia Post network, transportation connections and delivery arrangements.

Completeness is an assessment of the extent and range of the dataset with regard to completeness of coverage, completeness of classification and completeness of verification.
Attribute completeness
All attributes for each object are populated.
Temporal accuracy is applicable to most of the current release.
Quality scope
Polygon and point geometry accuracy and attribute accuracy for all included areas.
Geoscape data capture process
2017-01-24
The data is to a standard determined as fit for the purpose for which it was collected.
true
Logical consistency is a measure of the degree to which data complies with the technical specification. The allowable error in logical consistency previously ranged from 3% to 5%. The test procedures are a mixture of software scripts and onscreen visual checks.
The data structure has been tested for conformance with the data model. The following have been tested and confirmed to conform:
• File names
• Attribute names
• Attribute lengths
• Attribute types
• Attribute domains
• Attribute order in file
• Object type
• Compulsory attributes populated.
The data been thoroughly tested and is free of the following topological errors:
• Pseudo nodes
• Overlaps
• Bowties and other self intersections
• Duplicate features
• Incomplete polygons
• Gaps (voids and slivers) between polygons
• Object continuity at sheet edges and borders.

The data is to a standard determined as fit for the purpose for which it was collected.
true
Positional accuracy is an assessment of the closeness of the location of the spatial objects in relation to their true positions on the earth’s surface.
The positional accuracy includes:
• a horizontal accuracy assessment
• a vertical accuracy assessment
The horizontal and vertical positional accuracy are the assessed accuracy after all transformations have been carried out.
Relative spatial accuracy of the Administrative Boundaries dataset (i.e. Suburbs/Localities) used in the construction of postcodes reflects that of the source data.
Note
The accuracy of geometric representation is given by the difference between the position of the geometric representation of an object and its absolute position, as measured with respect to the geodetic network.

The data is to a standard determined as fit for the purpose for which it was collected.
true
Attribute accuracy is an assessment of the reliability of values assigned to features in the dataset in relation to their true ‘real world’ values.
Key attributes (postcode and the unique identifier) have a high degree of accuracy in the order of 99.09% and are reflective of the operational needs of Australia Post. Other attributes derived from the processing of supplied data may have a lower degree of accuracy but less than previously released data. The postcode allocated to an area may not be the same postcode as published by Australia Post through their website or other sources, as the postcode is some cases is based on the most commonly used postcode for addresses in a given area. All attribute accuracies are dependent on the data accuracy supplied to Geoscape Australia.
For this product, feature and attribute accuracy is a measure of the degree to which the features and attribute values of spatial objects agree with the information on the source material. The allowable error in attribute accuracy was previously up to 5%.
A precise attribute accuracy assessment may not always be possible. In these cases an intuitive estimate of the expected attribute accuracy or the likely maximum error based on previous experience is acceptable.
The postcode allocated to a gazetted suburb/locality is the most commonly used postcode, in a small number of cases the postcode is different to the postcode published by Australia Post on their website. These cases are due to changes to locality boundary or locality name, where the postcode remains the same for delivery purposes.

true
Topological consistency is the measure of how features spatially relate to other features within and across themes. Topological inconsistencies are identified using a combination of automated rules, and visual analysis. Where topological inconsistencies are identified they are notified back to the supplier organisation for remediation at source. Some minor topological inconsistencies are corrected during product processing using automated rules. The level of topological consistency is dependent on the data supplied to Geoscape.
During product processing there is no attempt to enforce topological consistency across state and territory borders. Cross border topological consistency is a complex issue and Geoscape continues to engage the Federal, State, and Territory governments of Australia to improve the topological consistency of spatial datasets across these borders.

All suburb/locality data used for the polygon geometry in postcodes is captured by the state and territory governments through appropriate agencies. The digital suburb/locality boundaries and their legal identifiers have been derived from the cadastre data from each Australian state and territory jurisdiction.
The postcodes are provided by Australia Post and are required to facilitate the efficient processing and delivery of mail to customers. Any areas that do not have postcode boundaries (e.g. NW South Australia) are consistent with the coverage of gazetted suburbs/localities boundaries. None of the gazetted suburb/locality boundaries have been changed with the exception of the suburb of Melbourne, which is split into two separate areas for the allocation of different postcodes (3000 and 3004).
A decision as to whether a new postcode or an existing postcode is to be allocated to a suburb/locality is based on operational efficiency. Issues that underpin the decision are critically analysed; these include the configuration of the Australia Post network, transportation connections and delivery arrangements. Australia Post will only allocate a postcode where there are deliveries within an area and where there is no conflict with the allocation of other postcodes by Australia Post. It is ultimately Australia Post’s decision on whether an area is allocated a postcode. Australia Post will allocate ‘NA’ as a postcode where they are unable to resolve the allocation of a postcode to a gazetted suburb/locality boundary, even though they may have identified a postcode for the name (e.g. GALIWINKU, NT). The postcodes for Australia Post postal services that use specific suburbs/localities, such as Post Office Boxes (e.g. EAST PERTH, WA 6892) are not captured in the Postcode Boundaries product.
