Take your party outdoors
This is the safest option, given most coronavirus infections are contracted in indoor spaces, where air currents mean that people generally end up breathing in other people’s exhaled air, even with physical distancing and air conditioning.
With some venues, it will be necessary to book your space. In Canberra, for example, the National Capital Authority (NCA) is promoting the idea that organisations could hold their function in the Old Parliament House Rose Gardens or on Aspen Island. In the spirit of holiday giving, the NCA will waive hire fees, so plan ahead and get in early.
Physical distancing is still important, even outdoors, so dancing, singing and close-up mingling should not be part of the plan. And the ground rules for the event should make it clear that anyone who is unwell, particularly anyone who has any respiratory symptoms such as a cough or cold, must not attend the event.
Hand sanitising stations should be readily accessible, and any hand hygiene risks anticipated and avoided as far as reasonably practicable. For example, you may consider asking people attending to bring their own plates and cutlery, and their own food and drink.
