Just regarding the discussion about the 'inquest' being a 'court' and whether it was regarded as an 'essential activity', from the Prime Minister of Australia's website about gatherings of over 100 people: BBM
"This does not apply to essential activities such as public transportation facilities, medical and health care facilities, pharmacies, emergency service facilities, correctional facilities, youth justice centres or other places of custody,
courts or tribunals, Parliaments, food markets, supermarkets and grocery stores, shopping centres, office buildings, factories, construction sites, and mining sites, where it is necessary for their normal operation (although other social distancing and hygiene practices may be required in these settings)."
