 There has been a notable increase in the population of students and the school has also been expanded to include 5 classroom 'blocks'.When Sancta Maria Catholic Primary School came in the year of 2010 they shared the same auditorium for assemblies and masses and so the college built a new gym for P.E.When it was first built, Sancta Maria College only supported students from Years 7–9, the same as Botany Downs Secondary College, due to lack of teaching space, but now it is a fully functional school from Years 7–13.
