The NSW Government has relaxed restrictions for places of worship and gyms as the state recorded two new locally transmitted cases of COVID-19.

From this Friday, the number of people who can attend religious gatherings will be lifted from 100 to 300, subject to the 4-square-metre rule.

COVID-19 safety marshals will only be required in gyms when there are more than 20 people in the venue at one time.

Currently a safety marshal has had to be present at all times, which has been a financial challenge for 24-hour gyms in particular.

NSW Treasurer Dominic Perrottet said these changes would have economic benefits and return more of society to the way it operated pre-COVID.

"This is a great announcement for the body and the soul," Mr Perrottet said.

Health Minister Brad Hazzard said religious leaders had expressed "concern and frustration" at having to turn people away from services.

"So the [increase to] 300 will make a huge difference," he said.

However, mass singing is still not allowed and Mr Hazzard has strongly advised those attending services to wear masks.

Mr Hazzard hit back at Hillsong Church founder and Pastor Brian Houston, who this morning told 2GB his church had been left behind.

"I have heard in the media, on 2GB, that some churches felt that they weren't being listened to. I assure you, you were and I'm sorry if you didn't think you were," he said.

"But unfortunately I heard those messages through the media, I didn't hear them to my office.

"Where we have had messages come to us, we have tried to to respond through exemption processes.

"For example, we have already granted exemptions to St Mary's Cathedral, St Andrew's Cathedral, the Auburn Gallipoli Mosque, the Central Synagogue."

Mr Hazzard said there was the possibility of an exemption for Hillsong to allow more than 300 people, given their church in Sydney's north-west can accommodate 4,000 people.

"But I'm not going to put a number on that because that requires the expertise of the Chief Health Officer and her team to look for each individual situation," he said.

The two new local cases of COVID-19 recorded in the past 24 hours are both linked to the cluster at the Great Beginnings Childcare Centre at Oran Park in Sydney's south-west, which now totals 22 cases.

There were also eight cases confirmed in overseas travellers in hotel quarantine.

There were 14,932 tests in the reporting period, compared to 7,401 the day before.

An alert has been issued for The Bavarian restaurant in Macarthur Square, Campbelltown, after a case linked to the childcare centre attended the venue on October 10.

Anyone who was at the restaurant for an hour or more from 7.00pm to 9.00pm is considered a close contact and must get tested and isolate for 14 days, even if the test is negative.

Anyone who dined outside or for less than an hour is considered a casual contact and should monitor for symptoms.

NSW Health's Jeremy McAnulty once again called for more testing, particularly in south-western Sydney, Western Sydney and south-eastern Sydney, where there have been local cases recently.

NSW Health is treating 72 COVID-19 cases, with one patient in intensive care.
