About NSW is a pilot project produced in-house at the Powerhouse Museum, Sydney. The idea is to access, aggregate and expose government cultural datasets to new audiences online. This includes making improvements to existing data sets so that they can be included on a map, in a timeline, or semantically linked to related data. The site is designed with citizens in mind and requires no specialised knowledge to use, other than the ability to browse web pages.
More info on the project is available here: http://www.powerhousemuseum.com/dmsblog/index.php/2009/09/02/introducing-about-nsw-maps-census-visualisations-cross-search/
and the site itself can be demo-ed here:

We recently did a mashup where we sourced data from our local GIS server, a client GIS server, and ArcGISOnline and presented data in a web application.
It would be wonderful to be able to get ABS Boundary data (or PSMA Data) available as a free online service that can be used in mash-ups.
I also think that this would make a great project that the taskforce could fund.

According to the PSMA website:
"G-NAF® (Geocoded National Address File) is Australia’s first authoritative geocoded address index for the whole country, listing all valid physical addresses in Australia. It contains approximately 12.6 million physical addresses, each linked to its unique geocode (that is, the specific latitude and longitude of the address). Data used to build G-NAF® comes from contributors that include the Australian Electoral Commission, Australia Post, state, territory and Australian Government mapping agencies and land registries.
G-NAF® is the single, national authoritative source for:
* validating customer-provided addresses (assisting in fraud prevention)
* identifying the geocode for spatial analysis (creating maps to plot and analyse services and customer locations), and
* assembling and maintaining large address files (reducing duplication and costs, increasing efficiency and improving mail delivery)."
Enabling access to this dataset would facilitate the linking of georeferenced information (datasets, reports, etc.) to relevant locations for mapping and research purposes.

To support agencies in mapping data to geospatial references, let's provide a central site which any agency can use to geospatially identify its data.
This could start by drawing on all local, state and federal government geospatial reference materials, building a single national service independent of any mapping solution.
This should include all electorates, postcodes, placenames and geographic features - but to preserve privacy not go to individual address level.
It can then be extended through crowdsourcing placenames, as the Victorian government has been doing at VICNAMES (http://services.land.vic.gov.au/vicnames/).
The outcome would be a central service that agencies, not-for-profits and commercial providers can use when matching data with geospatial references, enabling standardisation across emergency and other services.
