Oh look.

Yes — in any serious fuel rationing system, governments would almost certainly give priority access to workers and industries considered “essential” to public safety, health, food supply, and basic infrastructure.
In Australia, the existing emergency framework under the dcceew.gov.au� already identifies “essential users” who could receive fuel ahead of the general public during a national liquid fuel emergency. These include ambulance, police, fire, emergency services, public transport and similar critical services. �

Health care workers would very likely be prioritised, especially:
hospitals
ambulances
aged care
home nursing
medical supply transport
essential staff commuting where alternatives are limited
Farmers would also probably receive preferential treatment in a prolonged shortage because food production depends heavily on diesel for tractors, irrigation, harvesting and freight. While agriculture is not automatically listed in the core “essential users” legislation, governments can extend priority status during a crisis, and there have already been strong calls to prioritise farming in recent regional fuel shortages. �

Non-essential commuting and recreational driving would likely face the biggest restrictions first. Retirees would not automatically be excluded, but they generally would not receive priority unless they had essential medical or caregiving needs.
In practice, a rationing system would probably look something like:
Emergency and health services first
Food production and freight
Utilities and critical infrastructure
Essential workers with no transport alternatives
General public under capped purchases or ration cards
Historically, rationing systems usually try to guarantee minimum access for everyone while reserving extra supply for critical sectors. �
