You are right, botched figures.
Re-checked here:

Suncorp x 13 (including semis)
Gabba x 3
CBUS x 1
Townsville x 1
Belmore x 1
Canberra x 1
Cronulla x 1
Darwin x 1
NZ x 1
Penrith x 1
Bye x 3
So 17 games in or around Brisbane in total (+ 3 byes) 20 weeks of the season they are/were near home. So yeah.. didn't have to travel to Sydney much this season (3 games in Sydney in total, 4th being the GF this weekend).
Interesting when you look at when they played their games (regular season no finals)
Thursday = 4 games
Friday = 8 games
Saturday = 11 games
Sunday = 2 games
Compared to us:
https://www.nrl.com/draw/?competition=111&season=2023&team=500010
Monday = 1
Thursday = 0
Friday = 3
Saturday = 5
Sunday = 15
Can't be assed checking the timings of the fixtures but immediately you see they have 12 games at night in the season compared to ours which were majority day games.
Not sure if that's a big advantage, am sure it's nicer playing at night compared to day, especially if it's a stinker.
