The state government has issued advice about how to obtain a COVID-19 digital certificate to prove vaccination status but there are also options for those without the Check in TAS app.

This includes using the Express Medicare App, or accessing MyGov on a smart phone.

In the event that a person cannot use these to obtain their digital certificate, a hard copy of an immunisation history statement can be requested from a GP, which can then be shown at Check-In.

A printed copy of this statement can also be requested from the Australian Immunisation Register on 1800 653 809.

"If you can't get proof of your COVID-19 vaccinations online, you can ask your GP to print your immunisation history statement. Vaccination hubs can't print your statement or digital certificate for you," an Australian Services government website reads.

"You can also call the Australian Immunisation Register and ask us to send your proof to you. It can take up to 14 days for your statement or certificate to arrive in the post."

Royal Australian College of General Practitioners state chair Tim Jackson said calling the Australian Immunisation Register is advised, or alternatively get a friend or relative to help out for internet access.

"We are certainly there for our patients but by the same token we are all very busy at the moment, and patients are having trouble getting into see us," he said.

"The best thing to do is get a younger relative or friend who is good with the internet to help them."

While a hard copy can be obtained, the main way to obtain proof of a double-dose is through obtaining a digital certificate.

Digital proof can be obtained via the Check in TAS app over the coming days, where a green tick at Check In will indicate a double-dose vaccination status.

Anyone wanting to prove their vaccination status via the Check in TAS app must add their COVID-19 digital certificate to the app.

This certificate can be added to the Check in TAS app with the Express Plus Medicare App or Medicare Online on MyGov by following the "Share With" prompts.

Alternatively a hard copy of the digital certificate can be downloaded and printed.

Parents of vaccinated children who cannot prove their vaccination status through the Check in TAS app can download and print a hard copy of their child's COVID-19 digital certificate.
