Bishop McKenna's comments come after NSW Labor leader Jodi McKay joined with religious leaders in calling for amendments to the Public Health Order, to have the two square metre rule applied to places of worship.

Ms McKay also called for an end to the ban on congregational singing and chanting.

Bishop McKenna believes it's "common sense" to have the four square metre rule reduced to two square metres for churches.

"It would be a good thing and in fact it's what the Catholic bishops in NSW have been saying to the government for a while now," he said.

"I think it is common sense and all year the churches have been very cooperative, following all the guidelines. Certainly in the Central West, we've had no problems and I think not just because Christmas is coming, but it makes much more sense to come to the same two square metre rule that other venues have got."

Introducing a two square metre rule would allow churches - depending on their available space - to have up to double their current capacity, in the lead up to one of the busiest times of year.

Bishop McKenna said he "sympathises" with the government and the health authorities who had to adapt and work out regulations in light of the pandemic.

"Inevitably, when you bring in regulations, it turns out there'll be inconsistencies in them," he said.

"All we ask for is that the government has another look at it, realise where the inconsistencies are and make sure we safely and joyfully celebrate Christmas."

While Al Sahabah Mosque member Jameel Qureshi would love if restrictions were eased, he said he's happy to follow the advice from government.

"We'll leave that in the hands of the professionals," he said.

"They certainly know a lot more than us. I think we just need to be patient.

"I think Australia and New Zealand have been the benchmark for how to deal with the coronavirus, so I don't think we can argue with whatever they come up with."

Ms McKay said via a statement that the current restrictions are "unfair".

"40,000 people were allowed to attend the footy grand final and 1100 attended the Everest but there is still a maximum of 300 people for some of the most important religious gatherings," she said.
