your point is partly made CC. Whitlam lacked the discipline as did the cabinet. while their plans were strongly reformist and visionary.
in the balance at least Whitlam's problematic Govt more than made up by means of Medibank, enabling almost free health services, universal (free) tertiary education and several other important improvements that lasted more than a decade.
Whitlam;'s efforts were mixed, while Morrison lack any vision, made no improvements and significantly damaged the democracy thanks to his constant lying, blame shifting, lack of personal responsibility and his destructive influence on superannuation. his one single achievement was the National Cabinet.
wrt covid, he achieved nothing other than squabbling between the states and delivering the mRNA vaccines way late.
so do the equations for pros and cons and it easy to see that Morrison was indeed the worst PM in Aus history and his Govt the most ill-disciplined and damaging to the economy and infrastructure development.
for the latter just look at Taylor's mismanagement of Snowy 2..... it cost Aus taxpayers an extra $10Bn and a 4 year delay in completion.
