Meanwhile, McNamara has said that he would be surprised if his final World Cup squad does not contain any players currently plying their trade in the NRL.
There were no Australian-based players involved in England's first training camp of the year last weekend but the likes of Sam Burgess and James Graham are
expected to be integrated into the party
in the run-up to the World Cup, which starts in October.
"We've got a very good monitoring and analysis system in place in Super League and we've managed to apply that to the NRL competition as well," added the former Bradford Bulls coach. "It's given us a really good gauge as to where everybody is situated.
"I'm in constant contact with the group of players that we have in Australia and I will go out and visit them. They'll be kept fully up to speed as we move along.
"There will be players playing in the NRL that will join our group. I would be very surprised if there wasn't."
