There are a lot of reasons why this is not happening. Airlines are trying to recoup losses by charging the earth for flights to Australia, the most far-flung destination in the world. They can bring people in but not take them out so empty (ie no fares) flights are returning to UK, USA etc. Stopover airports have their own rules and restrictions, sometimes closing down suddenly or banning flights from certain countries. Crews are forced to isolate here. Maintenance staff for specific airlines are located at specific airports - again there are quarantine restrictions.We need to do more flights not less. We are effectively blocking citizens from returning home which is a disgrace.
