The Sydney MSIC client survey conducted in 2005, found that public injecting (defined as injecting in a street, park, public toilet or car), which is a high risk practice with both health and public amenity impacts, was reported as the main alternative to injecting at the MSIC by 78% of clients. 49% of clients indicated resorting to public injection if the MSIC was not available on the day of registration with the MSIC. From this, the evaluators calculated a total 191,673 public injections averted by the centre.
