Interstate travel is about to get a whole lot more fluid now that National Cabinet has pledged to reopen almost all borders by Christmas.

Of course, there will be caveats for individual states and territories.

Here's where you can go already, depending on where you're from, where you'd like to go and when you'd like to head there — as well as the changes that are on the cards.

Jump to the state or territory you're planning to travel to, to see what the rules are:

New South Wales

The NSW Government will reopen the border to Victoria at 12:01am on Monday, November 23, when all requirements for border permits and quarantine requirements will be dropped.

Before then, residents of a Victoria-NSW "border bubble" designated by the NSW Government can apply for a permit, but everyone else has to wait.

Under the "border bubble" rules, Victorians who live near the border can cross into NSW but must stay within the border region zone. They have to stay put if they've been to Melbourne in the past 14 days.

Other exemptions include year 11 and 12 students returning home, agriculture workers, people who need emergency care and people who are granted entry on compassionate grounds.

All other states and territories are allowed to enter NSW without going into quarantine on arrival.

South Australia

First things first, anyone travelling to SA must complete what's called a Cross Border Travel Registration form at least 14 days before you leave, regardless of where your travel begins.

This includes people entering from states and territories in the Low Community-Transmission Zone (at the moment that's every state/territory aside from Victoria).

It also includes essential travellers entering from Victoria and SA residents returning home from any state other than Victoria.

It doesn't matter how long you've been interstate for; for the time being at least, the form is a must.

SA officials are using the Cross Border Travel Registration form to work out whether incoming travellers are able to travel without restrictions, whether they're essential travellers and if they have self-quarantine restrictions, or whether they're unable to enter South Australia.

Before December 1, only essential travellers from Victoria are allowed into SA, but after that, SA will open its Victorian border and travellers from Victoria won't be required to quarantine.

Victoria

The Victoria-NSW border will open on Monday, November 23, with all border permits and quarantine requirements ditched.

The ACT will follow suit on the same date, saying it will be "consistent with the NSW approach, providing the COVID-19 situation in Victoria remains stable and there are no new concerns that arise".

Victoria is open to all other states and territories, but return travellers may have to quarantine when they get home depending on their own state or territory's rules.

ACT

ACT Health says on its travel page that it "does not declare areas safe or unsafe for travel", providing guidance instead.

In saying that, anyone trying to enter the ACT from Victoria will be denied entry unless they apply for and receive an exemption from ACT Health ahead of time. That goes for ACT residents making a return journey too, with returning travellers having to quarantine for 14 days on their arrival.

The ACT will follow the lead of NSW in dropping restrictions on travel from Victoria on November 23.

The ACT is open to all other areas in Australia.

South Australians can travel by air or road to the capital without having to quarantine, even if they transited through Victoria, so long as they didn't stop.

The ACT is also open to Tasmania, with travellers no longer having to apply for exemptions even if they've gone through Victoria (including those from the Spirit of Tasmania), provided they used "the most practical direct route" out of Victoria.

Tasmania

Everywhere in Australia, except for Victoria, is considered "low-risk" by the Tasmanian Government.

That means if you've only been in those "low-risk" places in the previous 14 days, you can go to Tasmania and won't have to quarantine. That's also the case for New Zealand.

Victoria is currently deemed "medium-risk", meaning travellers from there will have to quarantine for 14 days, but they can do so in a "suitable premises" or hotel quarantine.

If the current trends hold, Victoria will be moved to "low-risk" on November 27.

Western Australia

Western Australia was the lone holdout from Friday's National Cabinet meeting, when all the other states said they would open up before Christmas.

NSW and Victoria are still considered "low-risk" areas, which means travellers from those states have to self-quarantine or travel to a government-approved quarantine facility.

They will also have to present for a COVID-19 test on day 11 of their stay in WA.

Everywhere else has been deemed "very low-risk", meaning people don't have to quarantine on arrival.

Regardless of where people are coming from, travellers will have to go online and fill out a G2G pass registration before travelling and scan it on arrival.

Queensland

Anyone can enter Queensland without going into quarantine unless they have been in a COVID-19 hotspot in the 14 days before their arrival.

According to the Palaszczuk Government, hotspots still include the entirety of Victoria and the 32 local government areas that make up Greater Sydney.

The Queensland Government has flagged that border restrictions could ease by Christmas.

Regardless of where you're coming from, you'll need to fill out a border declaration pass to get into Queensland.

Northern Territory

Everyone travelling to the NT has to fill out a border entry form, but you will only have to quarantine if you have spent time in a COVID-19 hotspot.

Melbourne is the only region considered a hotspot by the NT Government. You can travel through Melbourne, provided you literally do not leave your vehicle (even for petrol) or leave the airport (if travelling by plane).

If you've been in a hotspot in the 14 days before reaching the NT, you will have to stay in supervised quarantine for 14 days at the Howard Springs facility or another approved facility.

You will also have to pay $2,500 per person for the stay.
