It appears that there is no national aggregation of this data, except at a high level (http://www.nwc.gov.au/nwi/biennial-assessments), but individual water authorities around the country, of which there are many, publish water quality data in their annual reports. There are national guidelines and requirements that all water authorities publish data on drinking water quality, however all this data with very few exceptions was only available in PDF reports, and nowhere centrally discoverable. Some examples below:
