BICWA has an excellent, easy to understand guide on their website https://www.bicwa.com.au/copy-of-covid-19-updates-1 providing more information on the rules and restrictions regarding moving your hives or visiting bee sites during the COVID-19 lockdown
If you are seeking information about going to your hives in response to the current bushfires please contact the Department of Fire and Emergency Service or your local government authority.
And just a reminder that all beekeepers have a responsibility to find out if there is a total fire ban in their area on any particular day. Please remember that it is illegal to light a smoker if a total fire ban is in operation. Go to https://www.emergency.wa.gov.au/#totalfirebans on any day for up-to-date information.
