Gastro is a Google Maps mashup of the NSW Food Authority's name-and-shame lists.
It collates the Register of Offences and the Register of Penalty Notices and displays the location of offending restaurants on a map.
The code behind Gastro (crawler + website) is completely open source, released under the MIT licence.
We use Bazaar for version control. Checkout the code with:

We want to make it easy for other people to use the NSW Food authority data.
You can find up-to-date data in JSON and GeoRSS formats on gotgastro.com.
