Slater, on the other hand, was known for his lightning speed and incredible try-scoring ability, earning him the title of the NRL's all-time leading try-scorer.
Both players have left a lasting legacy on the game, leading many to believe they are more than deserving of the Immortal title.
Former players and experts have weighed in on the debate, with some arguing that the criteria for Immortal status should be more stringent, while others believe that Thurston and Slater have undoubtedly earned their place among the game's all-time greats.
"This is a farce," said one former player.
"The Immortal title should be reserved for only the absolute best of the best, and I'm not sure if Thurston and Slater quite reach that level."
However, another expert countered, "Thurston and Slater revolutionized their positions and were instrumental in their teams' success for over a decade.
They absolutely deserve to be considered for Immortal status."
As the debate rages on, it remains to be seen who will ultimately be chosen to join the ranks of the NRL Immortals, but one thing is for certain - the passion and fervor of the NRL fanbase will not waver in the midst of this controversy.
