Australian international borders are opening: What is next?

The Australian Government has announced that the country's borders will be fully reopened on 21 February 2022.  Is this a return to the pre-COVID normal?

Australia will reopen to all fully vaccinated visa holders, welcoming the return of tourists, business travellers, and other visitors from 21 February 2022.  Those who are not vaccinated will be required to apply for a travel entry exemption and undertake quarantine if granted permission to enter the country.

The announcement by the Prime Minister created enormous excitement across a nation weary of enduring 2 years of isolation from the rest of the world.  Tourism operators expect less risk-averse younger backpackers and students to swiftly return to Australia and fill jobs in sectors experiencing chronic worker shortages.
