Knights CEO Phil Gardner has revealed that the club will take an "enormous" hit financially after losing three home games - and having two others affected by crowd restrictions - because of Australia's rapidly escalating COVID-19 crisis.

But Gardner is confident the Knights, who have been owned by the Wests Group since November 2017, have never been in a stronger position to withstand any commercial setbacks.

"The great thing for us is that we've had great crowds and great sponsorships all the way through this season," Gardner told the Newcastle Herald.

"So I would have thought this would have been a record year for the club.

"That's what we budgeted for, before the COVID.

"I would have thought we would have had a profit in excess of $2 million. But now, after losing those three home games, we'll just have to see how it all pans out at the back end of the year."

Under Wests, the Knights announced profits of more than $1 million for seasons 2018 and 2019. Last year their revenue streams were decimated by COVID but the club still managed to post a small profit.

Gardner was unsure how the bottom line will read this year, because funding from the NRL, which is spending an estimated $15 million a month to accommodate 13 teams in Queensland hubs, is likely to be reduced.

"We got a lot of help from the NRL last year," Gardner said.

"They organised some grants and rationalisation and were great with all the clubs.

"This year I don't know if they have the money to do it, so that's why we're not sure how it's going to all pan out. The capacity for the NRL to support the clubs this year will be diminished."

Gardner estimated the lockdown could cost the NRL's 16 clubs a combined $30 million.

"It's very different for every club, depending on their individual circumstances," he said.

"For us, we lost three home games. We really rely on the stadium.

"Given that the team are travelling well and are in the hunt for the finals, we'd have been confident for big crowds at those last three games.

"We would certainly have sold out all the corporate boxes and hospitality and all that.

"So it's going to be an enormous amount of money for us."

Having struggled for almost 30 years to stay solvent, the Knights would appear to have no such worries now, given the financial security provided by Wests.

"We're very lucky that the Newcastle Knights are owned by the Wests Group," Gardner said.

"Because of the strength of the Wests Group, we're confident we can ride out any inclement weather."

Gardner said all Knights members would be offered a refund for the last three games of the season.
