Australian Hotels Association (AHA) of NSW Orana delegate Joanne Blair says the industry is willing to do "whatever is necessary to keep life as close to normal for our customers as possible".

She said no one wanted a repeat of the two-month shutdown forced in March amid the COVID-19 pandemic.

"It is so important for our local economy and jobs for businesses to continue to trade and we'll all just have to adapt to the new measures commencing this Friday," Mrs Blair said.

NSW Premier Gladys Berejiklian revealed new measures including a cap of 300 people in a venue, cutting the number of people per table from 20 to 10, a requirement for dedicated hygiene marshals, and compulsory COVID-Safe registration, and more, as the number of COVID-19 cases linked to the Crossroads Hotel at Casula reached 28.

Mrs Blair, the owner of Dubbo's Milestone Hotel, says the government's move to halve permissible group sizes will "inconvenience some people but it is still workable".

"We've had many bookings over school holidays of extended family groups that ranged between 10 and 20 people, but I'm sure the community will understand and just reduce their booking size to a maximum of 10 people for now," she said.

While the sign-in procedure in place since the industry was permitted to reopen to diners on May 15 had recently been relaxed to one person per group, it would now be for every person again, Mrs Blair said.

"The NSW government is also asking us as an industry to be super vigilant on this measure to assist with tracing should a community outbreak occur," she said.

"This contact tracing information is not being collected when you visit the supermarket or the hardware store, so it means the local pub is now playing a really important role by being able to provide this information to [NSW] Health should a case pop-up in our region."

Mrs Blair reports "in general" people have been happy to abide by the restrictions, but urged patrons to ensure they wrote their name and phone number legibly at sign-in.
