The Dolphins are the favourites to join the pinnacle of club rugby league if the ARL Commission decides to go ahead with expansion.

They're currently mulling that over as the usual complaints and demand for compensation comes from clubland.

Raiders chief executive Don Furner has repeatedly said they're not opposed to expansion - especially since they're an expansion club themselves, having joined the competition in 1982.

Next year will mark the 40^th anniversary of the Green Machine's maiden season in the NRL, with the club and the ACT government already making plans to celebrate the occasion.

The Dolphins have massive financial clout and a group of their power brokers visited the Raiders' centre of excellence in Braddon during the season to get an insight into what kind of elite training environment's needed in the NRL.

They also have links with the Green Machine - their chairman Robert Jones' son used to play for them.

Furner said it was common practice for clubs to tour each other's bases - something the Raiders' hierarchy did before building the new headquarters, which only opened last year.

"We did have the Dolphins board and management down here earlier in the year," Furner said.

"They looked through our facilities. We gave them a really good tour and I know some of those guys.

"We've had a lot of the clubs through here - [Wests] Tigers, [Gold Coast] Titans - we've shown a few through."

Raiders prop Ryan James' future was still up in the air, with Brisbane Broncos football director Ben Ikin confirming their interest in the former Gold Coast captain.

James still has one season to run on his deal with the Green Machine, but they've allowed him to talk to other clubs to see if there's an opportunity to get a longer deal elsewhere.

The Broncos were considering offering him a two-year deal, with the potential for it to be resolved early next week.

What happens with James will play a role in Dunamis Lui's future.

If James stays then Lui will likely need to find a new home after five seasons in lime green.

He's also been linked with a return to the Broncos, where he spent four seasons.

If James goes then Lui could get a one-year extension, with the former Queensland Origin player keen to remain in Canberra.

"The club's in conversations at the moment with Ryan's agent," Ikin said.

Raiders fullback Caleb Aekins was yet to find a new home, although a couple of English Super League clubs have spoken to Canberra about the 23-year-old.

It's believed Salford and Castleford were the two clubs, while Leeds and Leigh have previously shown interest in the custodian.

Aekins was one of five fullbacks Raiders coach Ricky Stuart used following Charnze Nicoll-Klokstad's neck surgery, but he fell out of favour after getting first crack.

Nicoll-Klokstad's injury allowed the Raiders to show they have plenty of depth in the position, with Jordan Rapana, Bailey Simonsson and Xavier Savage all showing they can fill the role - especially in Savage, who generated plenty of excitement in his two NRL games before a shoulder injury ended his season.

They've also finally locked down another future option in the outside backs in Albert Hopoate.

The Canberra Times revealed in July he'd agreed to terms on a two-year deal, which has now been finalised and he'll join the senior squad next season.

But a halfback is top of the Raiders' shopping list and they've been linked with every playmaker coming off contract.

Parramatta five-eighth Dylan Brown's a name that keeps coming up, although he's contracted to the Eels until the end of 2022 - but can start talking to other clubs from November 1.

The Raiders have considered offering unwanted Titans half Ash Taylor a one-year deal, which would tide them over until Brown became available.
