Country Victorians have voiced fears that public transport could bring spread coronavirus the regions, as case numbers continue to climb in Melbourne.

Regional Victoria is currently largely free of the virus but one north-east resident said not enough was being done to monitor public transport

Iain Atkins from Violet Town said he was recently crammed onto a V-Line bus with more than 50 other passengers.

"This is exactly the way a spread into regional Victoria could occur," Mr Atkins said.

Coach replacement service crowded

On Tuesday, just hours before NSW closed its borders to Victoria, Mr Atkins was caught a coach bound for Albury.

V-Line has replaced all Albury line train services with coaches for all or part of the journey due to the border restrictions, but Mr Akins said this had resulted in passengers normally spread across four carriages filling one coach. 

Mr Atkins, who has multiple myeloma and a compromised immune system, regularly travels to Melbourne by train for medical appointments.

He said it seemed transport staff didn't realise they were in the middle of a pandemic.

"People were squashed onto one coach and almost every seat was taken."

The coach stopped at the hotspot suburb of Broadmeadows and around 15 more passengers boarded at stops on the way to Mr Atkins' destination, almost filling the bus.

He said he was concerned passengers could not physically distance on a coach.

"The issue is that people don't know if they have this thing, and anyone on this bus could potentially be spreading it up all the way along the north-east," he said.

In a statement a V-Line spokesperson said the service had increased cleaning across train carriages, buses, stations and stops, in addition to nightly sanitation.

The spokesperson said there were occasions when physical distancing on public transport "wasn't possible".

"The safety of our staff and passengers is our number one priority and we are delivering unprecedented cleaning and keeping services running to a full timetable in Victoria to ensure those who need to travel for one of the permitted reasons can do so safely," they said.

Police will conduct checks on train and bus passengers after a higher than usual number of tickets were purchased for regional trains in the lead-up to the Melbourne lockdown taking effect.

GP says responsibility with community

Shepparton GP Robert Campbell said the virus could become a serious problem for regional communities.

"It's sad that we have to police this because people haven't understood the significance," Dr Campbell said.

He said he was concerned people weren't doing the right thing.

"You're really relying on people minimising the risk of transmitting this because the virus doesn't spread — people spread," he said.

"It comes down to personal responsibility because if everybody had done the right thing, we would not be in the mess that we're in now in Victoria."
