I both agree and disagree with you ! Lots of scaremongering, yes, ridiculous. Australia wide death rate may not have varied much, but what about Victoria? Also easy to forgot that Australia, even Victoria in second wave has been very successful in controlling the virus. Would we be able to say the same had Victoria not controlled it and ended up with the same deaths per capital, as say New York State (ie >10,000 in total)? There’s an element of chicken and egg there.
Having said that , frankly the border restrictions are completely ridiculous, except those to metropolitan Melbourne. Look at place like Ballarat, there’s always a lot of movement between there and Melbourne, albeit much reduced I presume during lockdowns. But still, I expect there is some movement. Despite being only 80km or so from the major hotspots, only 50 cases recorded in the last two months. Yet borders have been closed for example between NSW and Qld,and even the COVID hotspots of Mildura (1 case in last 3 months - who advised local press she was in isolation in Melbourne) and Wodonga (also 1 case in last 3 months) being treated by other states the same as if they are in the epicentre. I remain sceptical that the national hotspot definition will achieve much other than opening VIC/NSW/ACT up (and maybe SA? ).
