The latest offical status, from the Prime Minister, Scott Morrison, regarding the list of businesses to shut down from midday tomorrow, Monday, 23 March:

Referring to the above list, and the specific mention of “hairdressers and beauticians”, my practice is effectively in a similar situation, since there is only ever one client present at any given time, and people are not congregating. In accordance with the official measures, my practice is open for the time being, pending further updates.
I will, of course, continue to monitor and will comply with the official government position and rulings.
