Covid-19 travel

Mandatory quarantine arrangements are no longer in place for interstate arrivals, other than persons arriving from an area that has been declared a coronavirus hotspot.

All people seeking to enter the NT must fill in a Border Arrival Form. This form is available online at coronavirus.nt.gov.au and at border access points.

Territory borders will remain closed to areas declared COVID-19 hotspots until further notice. Hot spots will be identified by State or Territory Governments, or by the Australian Health Protection Principal Committee, with updates listed on coronavirus.nt.gov.au.

Persons arriving to the NT from hot spot areas will be required to undertake mandatory supervised quarantine at a Territory Government approved facility at their own cost. Mandatory supervised quarantine will be at the Howard Springs quarantine facility or another approved facility elsewhere in the Territory.

Persons arriving in the NT from declared coronavirus hotspots must complete travel to an approved quarantine facility as quickly as possible, which must be no later than 72 hours after entry.

You cannot get into Qld because Qld has declared NSW and the ACT a hotspot - why ACT is a hotspot I do not know.

Does SA allow NSW travellers in? - I dont know but I think not - so as you have to go through NSW you probably cannot get into SA.

So unless you fly direct Canberra to NT then I think you cannot get into NT without at least some quarantine.

Instead of getting opinions from those who may or not know the correct facts, go to which ever state official web site.

NSW is your (only) oyster Bill - as long as you avoid Covid-19 hotspots, sanitize regularly, maintain social distancing and preferably quarantine when you return. Complacency wrt group gatherings has caused too many setbacks (at massive cost to jobs and the economy) already.
