Hotel quarantine is the source of many of the Covid 19 outbreaks we have seen in Australia. We are now seeing the virus transferred between travellers in adjacent hotel rooms due to the transmissibility of the Delta strain of Covid 19. 
Rather than bringing returned travellers into cramped hotels in the most highly populated areas of the country, we need to bring them back to custom, isolated facilities like Howard Springs in the NT where sufficient air gap between rooms prevents transmission.
Furthermore we need systems and strategies in place to ensure 100% prevention from future strains of Covid 19 entering Australia. 
Every subsequent strain of Covid 19 is more transmissible and more deadly. It’s time we acted to comprehensively 100% prevent future outbreaks of subsequent Covid 19 strains. Let’s keep our children safe from the next wave of this unrelenting virus!
