Well in the current rules here: https://www.nsw.gov.au/covid-19/what...do-under-rules
It says
Healthcare products and services may open including
... remedial or therapeutic massage service providers
Under personal services (so other than remedial or therapeutic massage) it says
Personal services -Closed
- Massage and tattoo parlours cannot provide services however they can open to sell products and gift vouchers. This applies to any business premises, regardless of whether it operates in a retail outlet or in a private home. Businesses must comply with the 4 square metre rule.
- Strip clubs and sex services premises are closed.
So remedial and therapeutic massage are already open
Then under changes for the 13th of June it says:
Personal services
- Tattoo and massage parlours can reopen with up to 10 clients.
Given that remdial and therapeutic are already open, and there are no stated limits on what sort of personal services massage may open on the 13th - just how many clients they can have - it is reasonable to think this included erotic massage. After all, what else could it mean? And if it did not include all forms of personal services massage you would reasonably expect them to have said so.
Note: I am not a lawyer, just reading the rules.
Personally I will wait, but it would seem to have have been in intention to allow erotic massage venues to operate.
Of course, this might get updated and the actual rules are what are declared by the chief medical officer at the time. We should probably check what they actually say come the 13th.
