Education · ACARA My School 2025
2 schools inside O'Sullivan Beach, plus the closest options around it. Distances are straight-line from the suburb centre and are not enrolment catchments — always confirm zones with the school.
ICSEA is ACARA’s official measure of a school’s socio-educational advantage — based mainly on parents’ education and occupation, plus the school’s location and student mix.
Why are some State Rank and star ratings blank? Schools can choose not to publish their results. In practice, schools that score well above their state average almost always publish theirs — so a blank rating more often reflects a school opting out than a top result being hidden. Academic results also tend to rise with ICSEA Rank, so higher-ICSEA schools more often carry a strong State Rank as well.
