"I think I've still got a fair way to go. Last year was my first year in rugby and I was pretty happy with how things turned out,'' Folau told AAP.
"I get another shot at this year to try and improve my game and be a lot more consistent.
"In attack, I can inject myself a little bit more and be a bit more creative and play a ball-playing role, try different things to add to my game.
"Taking it to the line and seeing opportunities, you have to make the most of it.
"I've had to work on it a bit - you watch different players and pick up different things. But as a fullback, you've got to have that as part of your game.''
The only problem the Waratahs face in playing Folau at fullback, is it will prove nearly impossible to fit fellow Wallabies Kurtley Beale and Bernard Foley in the starting team - given they'll have to fight it out for the five-eighth role.
But Folau was a revelation at the back last year for Australia under Ewen McKenzie, and the thought is you must play your best player in his best position.
As a result, he'll be handed the keys to the Waratahs' backline but, by incorporating ball-playing into his game, he'll be able to take some pressure off whoever lines up at five-eighth.
Folau and fellow Wallaby Michael Hooper will sit out the Waratahs' opening trial against Melbourne in Albury on Saturday.
