"I did not come to Australia to be a slave of whimsical government. You have not implemented risk-based management, no evidence-based policy, no cost-benefit analysis. No justification. Just whimsy," he continued.
The experienced public policy adviser in a later post to Twitter said that it is unfortunate that he had to leave the department and the role he loved to speak out.
"I considered deleting the few direct criticisms, but they wanted all indirect criticism removed too. I resigned on the same day, the only honourable course for a free citizen of Australia," he said about the meeting.
Sabhlok described Australia's, in particular, Victoria's response to the COVID-19 pandemic as "the most heavy-handed possible, a sledgehammer to kill a swarm of flies," he wrote.
Stage four lockdown started Aug. 2 after a series of strict measures to control the spread of the virus.
Measures include mandatory masks everywhere in public, no travel beyond five kilometres, and only two hours outdoors for exercise unless it's for work, essential shopping, or care-seeking or giving.
Sabhlok wrote in a Twitter post that COVID-19 spread was a chance to devise different responses to China where the virus originated.
Sabhlok said he repeatedly raised his views in his public sector capacity, but his attempts were rebuffed.
"The bureaucracy has clamped down on frank and fearless, impartial advice, in a misplaced determination to support whatever the government decides, (instead of performing its taxpayer-funded duty of providing forthright analysis of alternatives), he wrote in his opinion article in the AFR.
Premier Andrews played down that he is not open to public sector advice.
