Some interesting data on the rate of false positives from rapid antigen tests.

The samples were taken from more than 900k compulsory tests across 537 workplaces which returned 1,322 positive results with 462 false-positives (42%), however 278 of those false positives came from a single batch of Abbott’s Panbio COVID-19 Ag Rapid tests which suggests the batch itself was faulty and the overall false positive rate is therefore closer to 13%.

Of more importance is that there were only 12 false-negatives confirmed amongst those 900k tests which supports the view that a false-positive is a much greater risk than a false negative even if the TGA doesn't agree.
