Riverwalk There are still people coming into Australia. Victoria has on average about 1100 per week arrive from overseas and other States are also allowing a similar number of arrivals. They are not travellers as such but they have travelled to Australia from places where the virus is more active.
Among others arriving from overseas there are those associated with the tennis,
a French politician arrived in South Australia during the week with an exemption from quarantine,
Australian citizens/residents returning home - as is their right-, many after several false starts,
some "celebrities" come in. Matt Damon arrived last week Tom Hanks arrived not too long ago and there have been others,
the Indian cricket team were here and there have been various other exceptions.
So, the borders have not been closed totally as many think and are led to believe.
Callistermon I agree with you but under our lockdown laws we can only travel 5 kilometers from home, had the people at the tennis been able to stay beyond midnight they in many cases would have been in breech of those rules. Yes an exception could have been made but than you would have others wanting their activity exempted too.
It matters little what the virus is called however, our authorities and others throughout the world are using the term UK strain I'm sure this is not meant to be a slight to the people of UK but it identifies the strain as being different to the one we had been dealing with. It was not Australia who named it as such or NZ
