Premier Daniel Andrews said nobody should be racially abused, adding the bus driver was one of many essential workers doing it tough during the pandemic.

"He is doing really important work and he is putting himself in harm's way in terms of the virus and all the pressures and challenges that he is facing," Mr Andrews told reporters on Friday.

"No-one deserves to be treated like that and it is simply wrong. But I want to say thanks to bus drivers, truck drivers, people stacking shelves, to everybody who is working hard for Victoria, thank you."
