During Collingwood's 69-point win against Gold Coast, the small forward found 12 disposals and kicked 2.2 to continue a strong return to the side from injury.
Elliott, who missed all of the 2016 and 2018 seasons with injury, was pleased the milestone meant spending quality time with his family.
"I had my family down last night which was a little bit chaotic with my nephew and niece running amok," he said.
"I get to spend a little bit of time with them now, go out for dinner, relax and take it all in, and then focus on next week."
Elliott, who will be desperate to retain a spot in the Magpies' line-up after missing the grand final run last season, was happy with his performance in his 100th game.
"It's always nice to kick a couple of goals but it's even better when you win by a big margin and win games," he said.
"We had a good even spread of goal-kickers, hopefully Jordy (Jordan de Goey) comes back soon and we get 'Stevo' (Jaidyn Stephenson) later in the year, they'll add so much to that forward line."
Tallygaroopna's Steele Sidebottom was also in fantastic touch, with 27 disposals and two goals.
For the Gold Coast, Mooroopna's Jarrod Harbrow found 18 disposals.
