For most St Marys buyers, air quality will not be a dealbreaker. The region around 2760 is unlikely to be materially worse than the Sydney metropolitan average. It becomes more relevant if you are comparing St Marys to suburbs further from major road corridors, or if a household member has a respiratory condition that makes air quality a daily health consideration rather than a background factor.
