Bribie Island Square sounds like a retail or civic precinct that someone once also marketed as a stay. The old directory filed it under accommodation. We keep the slug and treat it as a historical mention.
Squares and shop clusters on Bribie sit in the townships, which is useful: you want coffee and a chemist more often than you want a dune. They are not a national-park address.
Details unverified. Do not assume apartments still sit above a particular arcade. Use a current map and a current booking tool.
For planning, Bongaree’s precinct is the arrival cluster after the bridge. For a swim, leave the square idea and read beaches.
