As I live in Melbourne and we have been in fairly strict lockdown conditions for 9 weeks now it is very easy as there are lots of testing sights around. I just walked up to the local community health centre about 10 minutes away and said I wanted a Covid test. Waited while they dealt with the two people in front of me, answered their questions as they took my details then waited for the nurse. Took about two minutes for her to do her bit and that was it. The swab up each nostril was a bit unpleasant. Then home to isolate until the results came which took 32 hours.
