Rugby league's age-old Immortal debate just got juicier with the prospect of two additional Immortals being added to the game's most prestigious club in 2018.

NRL CEO Todd Greenberg confirmed the Immortals relaunching alongside modern day greats Wally Lewis, Mal Meninga and Darren Lockyer on Monday, with an induction to now be made every four years.

Meninga and Lockyer will be among many contenders for inclusion in the current eight-man Immortals group alongside the likes of St George icon Norm Provan, Roosters great Dally Messenger, legendary halfbacks Peter Sterling and Allan Langer, Ron Coote, Brad Fittler and record-breaking 1930s centre Dave Brown. The judging process will run up until an official vote in July.

The NRL is also revamping its Hall of Fame, with another six retired stars to be inducted alongside the inaugural 100 players first named as members during the 2008 Centenary Year celebrations.

Having now been officially brought under the NRL's banner, both the Immortals and Hall of Fame will have new eligibility criteria and structures outlined in a bid to add prestige and transparency around the game's highest awards.

"This is a significant occasion for our game as we celebrate the history of rugby league and recognise those who have shaped it," Greenberg said.

"Without question, one of the biggest topics in rugby league revolves around comparisons between heroes of our game… whether it's players from decades ago or those from the modern era.

"This year, we will induct an additional six players into a new NRL Hall of Fame.

"They will join the 100 Greats – named in our Centenary year 10 years ago – who gain automatic induction into the NRL Hall of Fame as the Charter Class.

"We will also relaunch the Immortals, with up to two players being given the ultimate honour in our game, every four years.

"And the first of those new Immortals will be chosen this year."

Hall of Fame & Immortals program explained

Under the NRL's new structure, a 'final five' players in contention for Immortal inclusion will be decided by May before the panel votes on the latest inductions.

The Immortals voting scope will also now cast all the way back to 1908, bringing the likes of Dally Messenger and Dave Brown into contention for the honour.

With six new Hall of Fame inductees to come mid-way through the year, a list of 25 contenders will be announced next month, with coaches, referees and contributors to the game also be recognised from 2019.

As with the Immortals, Hall of Fame inductees must be retired for five years before consideration, with a maximum of four players to be announced each year.

NRL Awards Manager Frank Puletua said the new recognition programs are a significant step in rugby league's celebration of its past and greatest individual achievements.

"With the inclusion of the Immortals, the NRL now has more than 30 official award categories in our game – ranging from those who reach 100 NRL games, through to our top tier awards such as the Dally M Medal, Hall of Fame and Immortals," Puletua said.

"A significant amount of work has been undertaken to ensure that our history and tradition continues to appropriately acknowledge milestones and pay tribute to the best of the best."
