Victoria has updated it's restrictions on their coronavirus.vic.gov.au webiste, which are as follows.

Face Masks

From 11:59pm on Sunday 17th January 2021, face masks will no longer be mandatory in all public indoor settings.

They will be mandatory in the following locations:

• on public transport
• when riding in a ride share or taxi
• in large retail stores (over 2,000sqm), such as department stores, electronic stores, furniture stores, hardware stores or supermarkets
• inside shopping centres, including the retail stores inside shopping centres, such as clothing stores. (If you have a clinic inside a shopping centre, masks must be worn)
• inside indoor markets
• on domestic flights to and from Victoria
• at airports
• in hospitals
• when working in or visiting hospitals and care facilities (if you have clients in aged care facilities, you will need to wear a mask).

You must always carry a face mask with you when you leave home unless you have a lawful reason not to. It is also recommended you wear a mask if you cannot keep 1.5 metres distance from others.

Working from Home

You must have a COVIDSafe Plan in place, and the work space is subject to the density quotient and cleaning requirements as per other work settings.

Home-based businesses no longer require a discrete work area in order to operate, subject to the restrictions of their industry.

Mobile Clinic Services

At this time, the Victorian government has not been clear about this activity, however, based on the information relating to other industries, access private residences, face masks and the ability to now work from a home-based business, it appears that the government will allow this service. You should use your own discernment in relation to wearing a mask. It is not required in a private residence, but if you are entering a residence that is not your own you should consider the ability to control the environment and the whether you should be wearing a mask.
