Folau is still yet to play his first game of senior union since his high-profile move but his ultimate aim is a spot in Robbie Deans' Wallaby squad when Britain and Ireland's elite come calling in June of this year.
The 23-year-old is realistic about his prospects of completing a remarkable rise in just four months of action, however, and he insists he's only thinking one step at a time ahead of his side's Super XV opener against the Reds on February 23.
"Everyone would love to be a part of that big (Lions) campaign, but my main focus is to try and get a spot in the team for the Waratahs first," Folau told Australian reporters.
"Hopefully if I am playing good rugby... we will see what happens. It would be nice to be a part of it, but I'm not looking that far ahead.
"I feel pretty good since I started on day one with all the skills and stuff. (But) my body took a bit of time getting used to all the contact. I have missed it for a couple of years, just trying to get my body used to the hits again. That probably took a couple of weeks."
Folau shone as a wing then a centre during his time in the NRL but no decision has yet been made on where he will feature in the 15-man version of the sport.
Midfield may well be his long-term destination given his eye for a gap and his all-round skill set but he has spent his initial training sessions a little more detached from the action.
"I am pretty open minded to whatever position 'Cheik' (Waratahs boss Michael Cheika) wants me to play in the backline, but at the moment I have been training at wing and at fullback," added Folau.
"I certainly feel comfortable in those positions. I guess it is a different story when it's time to play, but we will see how we go.
"The main thing for me... when I am really happy that transfers on to the field where I start to play good."
