More than half the kids enrolled at school in the ACT missed the last two attending days of the first term because parents knew the schools were considering a move to a lockout (which meant remote learning). Messages were being sent around saying that the schools were open and the children were expected to attend, yet only half did. I am not criticizing the parents in this.
Looking at RPT aviation, lets say the flights are there and its $80 each way from Melbourne to the Gold Coast.
People will want and need to go from home to the airport then a plane, another airport, the hire car, some crappy tourist attraction, the beach ... then reverse the steps before Monday morning. All it will take is one person sneezing at the back of the plane for everyone else to think "maybe this wasn't a good idea".
To your point Bruce, legislation be buggered. it will be up to we the people to decide what risks we are willing to accept and we will be deciding on a daily basis once the legislature and law enforcement stop being pricks in public - beaches and cafes are just really easy for plod to get to and be seen at. At the time DA and his mates decide to actually promote not staying home, we will see that people really want to go to the beach and all the rest of it. The pent up demand will be huge. Cinemas, football matches, airline travel, festivals, trade shows, The Royal Easter Show, Farmfest, the dreaded Maleny Folk Festival will be things of the past. They will be sacrificed not because they are dangerous but because not enough people will go to make them financially viable.
