Pharmacist Greg Shearing, on the front line of keeping community members well, echoed the parliamentarian's view, saying he was "shocked" by the incident.

NSW Police fined the tour company $5000 for breaching a public health order after it tried to take three busloads of travellers to Taronga Western Plains Zoo on Monday.

On board was at least 76 people who were not permitted to travel outside Greater Sydney under the restrictions imposed on Saturday as the NSW government battled to contain COVID-19.

The struggle continued on Thursday as locally-acquired cases in the state reached 195 since June 16.

Mr Shearing, a long-time pharmacist in Dubbo, took a dim view of the breach.

"I was shocked that a commercial operator would make, what appears on the surface, to be a conscious decision to so flagrantly flout the rules and with such large numbers of people," he said.

"Very disappointing. Let's only hope they haven't been spreading on their travels."

Mr Saunders, who had to go into isolation late last week and have a COVID test after a colleague tested positive to the virus, underlined the gravity of the breach.

"I was extremely disappointed to hear about the travel company which breached the public health orders earlier this week," he said.

"I want to commend the staff at the zoo who followed their COVID-19 protocols, identified the breach and reported the matter to police.

"In doing so, they have protected the rest of our community. Thank you."

Mr Saunders said the incident showed why abiding by the restrictions was so important.

"The NSW government has placed more than five million residents into lockdown, and the majority of those people are doing the right thing," he said.

"But we can't police them all. So it's vital the rest of us follow the public health orders around physical distancing, visitor limits at home and in businesses, and mask-wearing."

The MP advised that if people suspected someone was in breach of the orders, they could report it to Crime Stoppers on 1800 333 000 or at nsw.crimestoppers.com.au.

"To anyone who has been in Greater Sydney in the past 14 days, please consider the health and safety of others and follow the stay-at-home orders," he said.

In total across NSW, 34 penalty infringement notices (PINs) were issued on Monday and of those 16 were $200 infringements for failing to wear a fitted face covering.

Police have been out and about ensuring the orders are complied with and another 59 PINs were issued on Tuesday, with 43 of those being for failing to wear a fitted face covering.

On Wednesday another 65 PINs were handed out, 52 of which were mask-related.
