1 Billy Slater (Melbourne Storm)
There was a school of thought that Billy Slater might have been a little passed it but he has come over his injury concerns and is amongst the very best fullbacks in the game once again.
He set the league and the State of Origin arena alight once again as a huge part of the dominant Storm and Queensland sides who won the Minor Premiership and Origin series respectively.
Slater managed seven tries during his 18 appearances this season, a decent return in a star-studded side which handed most of the four-pointers to wingers Josh Addo-Carr and Suliasi Vunivalu. His efforts in corralling the defence and leading from the back have made a huge difference to how the Storm have fared.
Slater has been far and away the best fullback in the NRL during the 2017 season.
2 James Tedesco (Wests Tigers)
It's fair to say that James Tedesco was the shining light in an otherwise dreary season for the Wests Tigers. His new club, Sydney Roosters, have plenty to look forward to in 2018.
The New South Wales Blues fullback put in strong performances in a losing series during the State of Origin period. In the league, he gave everything in a Tigers side that spent much of the year getting belted from pillar to post before an upturn towards the end of the season.
Tedesco managed five tries in 21 NRL appearances but it was his consistency under the high ball and strong kick returns that earned him plenty of plaudits. Teddy is an electric ball-runner and provides a much-needed spark to any team he plays for.
The Roosters have nabbed themselves a tremendous player for 2018.
3 Darius Boyd (Brisbane Broncos)
Darius Boyd's importance to the Brisbane Broncos was underlined perfectly by their poor performance in last night's qualifying final loss to the Sydney Roosters.
Boyd is the perfect custodian and Wayne Bennett clearly rates him, having signed him for the Dragons, Knights and Broncos during his career.
Darius is hugely important in the long, sweeping back line plays that bring the Broncos and the Queensland Maroons plenty of points. His ability to sniff out a try and his safety in defence make him a valuable asset.
4 Tom Trbojevic (Manly-Warringah Sea Eagles)
The Manly-Warringah Sea Eagles have proven plenty of pre-season experts wrong with their performances in 2017 and much of the credit for that must go to their electric fullback Tom Trbojevic.
Best known as Tommy Turbo, Trbojevic is building the same sort of Premiership-winning partnership with Daly-Cherry Evans that the erstwhile Brett Stewart had with the dynamic half-back, and that bodes well for the Silver Tails.
12 tries in 22 games, including some phenomenally athletic four-pointers which would prove incredibly important to the Sea Eagles' cause, see Trbojevic amongst the best fullbacks in the league and, in all honestly, he could be at the very top of the list as soon as next season.
5 Roger Tuivasa-Sheck (New Zealand Warriors)
2017 was an absolute nightmare for the Warriors having fallen well short of the finals altogether. Roger Tuivasa-Sheck has sometimes been criticised for drifting in and out of games but much of that has been due to the teammates around him.
On his day, RTS is one of the most skillful and complete custodians in the game, with an incredible knack for finding the try-line whilst being safe at the back.
With things in dire need of fixing over the ditch, Tuivasa-Sheck is the sort of player that coach Stephen Kearney, or any potential replacement, can build around.
