By now, most of us are accustomed to wearing face masks, but there are exemptions under the current Public Health Order.
NSW Health lists examples of those lawful reasons as "if you have a physical or mental health illness or condition, or disability, that makes wearing a mask unsuitable.
"For example, if you have a skin condition, an intellectual disability, autism or trauma, you are not required to wear a mask."
It also states "if you have a condition that prevents you from wearing a mask, you may wish to ask your registered health practitioner or disability care provider to issue a letter confirming this.
"However, this is not a requirement under the public health order."

Jessica O'Brien is a young mother in Dubbo who has a medical exemption from wearing a face mask. She says most businesses have been understanding, but has had a recent experience where she was flat out refused entry, and was not able to attend a friend's birthday party.
"You really need to be considerate that not everyone can wear a mask," she said.
"It is actually really traumatic sometimes, for people to demand to know your medical history as to why you can't wear one.
"I have a few reasons myself - such as being asthmatic and having a recent hyperemesis pregnancy where I was constantly vomiting and I can still sometimes be triggered and feeling like I can't breath when my face is covered - those kind of things you are more likely to share.
"But if you've been the victim of something such as domestic violence, you're not going to want to share that in public."
Under the current health order, you're required to wear a face mask in non-residential indoor areas, which includes "retail or business premises that provide goods or services to members of the public who attend the premises".
Business are required to enforce this rule, as well as the mandatory checking in using QR Codes.
Ms O'Brien is calling for tolerance from businesses and from the wider community when it comes to people who have genuine reasons for not doing so.
"It's actually really isolating, especially having a young baby and being at home the majority of the time," she said.
"It might seem reasonable while the mask mandates are only a week or two, but as it keeps getting extended, are you really going to tell people they can't participate in society?
"Especially if they really need social contact for their mental health."
A NSW Police spokesperson said, "Business owners/managers can refuse entry/service to people who are not complying with the Public Health Orders.
"Obviously, they should gauge the situation and assess whether refusing someone may escalate and heighten the risk of violence or harm to themselves, their staff or other customers.
"If a situation does escalate and there is a risk to safety, they should call Triple Zero (000) or their local police."
