The Newcastle Knights will table a proposal to play a double-header with A-League counterparts Newcastle Jets in a revolutionary alliance between the rival football codes.

Just days after warning Knights fans the club could be lost forever if crowd numbers didn't increase, Knights chief executive Steve Burraston revealed he would explore the possibility of a staging a Knights-Jets fixture on the same card.

"It's something that could be attractive to the people of Newcastle," Burraston told The Sun-Herald.

"It's something we've thought about. I know the fields are different and there are logistical problems, but it's a possibility.

"The only difficulty is the field and it comes down to the grass - soccer is played on different grass to rugby league. It could certainly be attractive if we could work out how we could cater for the two fields on the same day, it may be something there is a will for.

"There are smarter minds than mine that can work out a way to do that."

Burraston is yet to put the proposal to Jets owner Con Constantine or chief executive John Tsatsimas, but is hopeful the pair will embrace the radical plan.

"We meet up about once a month for a chat just to catch up," Burraston said. "We've run some figures in the past in terms of training together and playing [training] games against each other, but I've had no formal discussions.

"That could be on the table the next time I have a coffee with Con and John. It's something we can put out there and see what their thoughts are."

Sydney-based rugby league clubs have been forced to look at alternate revenue streams after being hit hard by the new poker machine taxes and smoking bans at leagues clubs.

While the Knights have not directly been affected by those forces - they are not propped up by a leagues club - they too are struggling to stay afloat.

The Knights have averaged a home crowd of 19,020 this season, while the Jets averaged 13,209 in their matches at EnergyAustralia. But the prospect of both sides playing on the same bill is a potential stadium-filler if a venue can be agreed upon.

The idea is one of several radical proposals that have been floated to increase club coffers. There is also a push to stage a Super 14 fixture back-to-back with an NRL match, while Manly chief executive Grant Mayer suggested a whole round of the NRL could be shifted to Queensland.

"We're going to work hard to try and get that up for next year," Mayer said. "It hasn't been killed off and the NRL are going to do some numbers on it.

"We may modify it slightly to play out of two grounds instead of one.

"If we can tag it to a tourism event such as EKKA in Queensland, I don't think any club would sneeze at another $60,000 to $70,000 to their bottom line. There will be a thousand other ideas we'll look at."

Burraston, who was appointed to a committee to review the league's convoluted organisational structure, said Knights fans had to vote with their feet or risk having the club privatised, relocated or wound up altogether.

"I'm not being critical of our fans and I do understand the pressures that are being applied to families," Burraston said. "There are high interest rates and petrol prices, rents have gone up, the cost of goods have gone up. I'm not … telling them to come to the footy instead of eating.

"But people also need to understand there is a cost to our business.

"I wanted to flag it now rather than get two years down the track and say, 'Sorry, we're broke', or 'We're on our way to Adelaide'."
