I forgot something, Mousey. Welcome to AFF
Australia is not currently a
country with a US quarantine requirement, but you can expect other countries to be added to the list once they reach the threshold of “sustained local transmission”. At current spread this may be days away in Australia, or the US may order a general inbound international travel restriction as many other countries have done.
California has just proclaimed a
stay home requirement for everyone. We don’t know what exactly this means, but based on what is happening in many countries there is the risk you would be turned back, as your travel is not essential.
Something new every day, and noone can give definitive advice about tomorrow.
