I think the best case scenario once restrictions are lifted and massage shops (relaxation) open is that virus cases stay low and restrictions aren't re-tightened.
But shops need to consider an alternative method of operation ... like setting up girls to work individually elsewhere (apartment ... can be rostered to share across the week) or home visits.
Because ... Australia has taken a very conservative stance on this. If virus numbers come up ... then the restrictions may return.
That's also why (in my opinion) it's a good idea to use the CovidSafe app so that tracing of contacts with a positive treated person can be effective as possible.
