In yet another sign that getting vaccinated against COVID-19 is your ticket out and back into the country, people flying into Australia now have to declare their vaccination status. 

The Australia Travel Declaration (ATD) form has been updated to include additional questions. 

Prime Minister Scott Morrison said the states would get the information to help them determine how to manage arrivals in the future. 

"The states will be in a position then potentially to look at how they're managing quarantine operations in their state … to look at ways that vaccinated and non-vaccinated travellers can be treated in the quarantine program," he said last week. 

"Obviously, those who are vaccinated have a much lower risk of infection than those who are not vaccinated." 

Here are the questions you will have to answer (when you get the chance to fly):

Returning Australians, as well as visitors, will be asked if they have ever been diagnosed with COVID-19.

If the answer is yes, there are further questions to be filled out, such as the time and place they were infected.

At the moment, anyone who flies in from overseas must spend two weeks at Howard Springs facility in the Northern Territory or a hotel quarantine in other states. 

However it is expected that travellers vaccination history will eventually determine what sort of quarantine they complete, and that is why the questions have been added. 

It comes ahead of a trial in South Australia that will allow a group of people to quarantine in their own homes if they are fully vaccinated. 

If successful, other state governments are expected to roll out the program. 

The updated form asks travellers if they have ever received a COVID-19 vaccine and requests evidence. 

In Australia, your immunisations are recorded and you can either carry proof on your phone or get a copy if you log into your myGov account.

There is a particular form to fill out if you have had just one dose. 

You will have to declare the date, location and brand of your COVID-19 vaccination.

But if you have had more doses, you will need to fill out a longer form, with yet another form offered if you have had three doses, in a sign that authorities are expecting people to get booster shots.

The questions on all forms include whether you have had one or two doses, the dates, type of vaccine and where.
