Great news the BCC are publishing water testing results weekly -see link
Shorncliffe Jetty and Sandgate/Brighton have very different results.http://www.brisbane.qld.gov.au/2010%20Library/2009%20PDF%20and%20Docs/5.Community%20Support/5.4%20Emergency%20management/Enterococci_sampling_Results_Week_1_1.xls
Cabbage Tree Creek is fine? 40 parts per 200 mL. I'm suprised there was even 60 parts per 200 mL at Sandgate. That E. Coli is pretty harty.
