This is what Australia is currently doing looks sensible if you can actually get a flight. Our system will no doubt be less rigorous.
Individual exemptions
The Commissioner of the Australian Border Force may grant you an individual exemption if you are:

Providing critical or specialist medical services, including air ambulance, medical evacuations, and delivering essential medical supplies
A non-citizen with necessary skills or working in a crucial sector in Australia
A non-citizen sponsored by your employer to work in Australia in an occupation on the Priority Migration Skilled Occupation List (PMSOL)

Travelling for compassionate and compelling reasons.
You must hold a visa and an exemption to Australia’s travel restrictions before you travel. You can request an exemption online and must provide appropriate evidence to support your claims. Requests may be finalized without further consideration if insufficient evidence is provided. All documents need to be officially translated into English.
You need to apply for an exemption at least two weeks, but not more than three months, before your planned travel.
To complete a travel exemption request, you should already hold a visa, and you should provide information and documents to support your claim. Proposals may be finalized without further consideration if insufficient evidence is provided. This may include the following:
Proof of identity
Proof that you hold a valid visa
Travel itinerary
Marriage, birth, death certificate/s
Proof of relationship or residence (such as a shared tenancy agreement, joint bank account, etc.)
Letter from a doctor or hospital, indicating why travel is necessary
Letter from an employer indicating why travel is necessary
Supporting letter from a business or government agency, advising why your skills are critical
The statutory declaration to support your claims.
