Please put some effort in getting information instead of creating straw man. NSW and Victoria are in a lockdown to have time to get 70-80% of eligible population double-vaccinated. Modelling by couple of institutes show that if lockdown ends today, hospitals would be overwhelmed and lots of preventable deaths occur. By all estimates we would reach that 70-80% number in 1-3 months time, so that's the plan. Google for "Doherty Institute planning", visit https://covidlive.com.au, check daily press conference of VIC and NSW premiers - answers to your questions are in plain sight.
