Yes say some, no say others.

The public transport union wants wearing masks on buses and trains made mandatory. But some experts are taking a bet each way.

Acting chief medical officer Paul Kelly said Australian health protection committee guidance suggests masks are not needed in most circumstances for most people, most of the time.

"However, there are some times when masks can be part of a solution and one of those would be where there's a large increase in community transmission and social distancing cannot be guaranteed."

"You can't guarantee social distancing on public transport, " Labor's Chris Minns said.

He said he had urged the NSW Minister for Transport to issue advice for people to wear facemasks on public transport, and to investigate whether NSW should follow the lead of cities around the world and make face masks compulsory on public transport.

MP Mark Speakman, who has responsibility for the administration of justice in NSW, said he deferred to the expert medical advice being received by Australian governments from their health officers.

"Circumstances may change quickly, but there still remains no recommendation to wear face masks for the general population who are not symptomatic and not in coronavirus outbreak zones," he said.

"However, the NSW chief health officer has said that masks can be considered as an option in settings where you can't socially distance."

So, basically, it is up individuals to decide, or as one reader put it, "If you think it makes you and those around you safer, wear a mask, if you don't, then don't wear one." It is up to you.
