But once the ad was posted to social media over the weekend, Szubanski has been hit with a social media backlash from "trolls" and "flat out covid deniers":
Szubanski also revealed on Sunday that coronavirus conspiracy theorists had visited her home address, putting a bizarre postcard warning of "mask scams" through her letterbox:
The video is part of a government TV campaign, which also features well-known Victorians including AFLW player Tayla Harris, The Project host Waleed Aly and actor Shane Jacobson.
Victorian Premier Daniel Andrews defended the new ad campaign in a statement over the weekend.
"As part of the latest in the Victorian Government's communications campaign, some of our most-loved Victorians are here to remind us all – staying safe is in our hands," he said.
"That includes small but simple things like wearing a mask, washing your hands, keeping your distance – and getting tested if you have symptoms.
"Using Victorian voices and a very Victorian sense of humour, this is the latest in our ongoing advertising and communications efforts and will be successively rolled out on social media channels in the coming days."
