The Australian Combined Schools Music Festival (ACSMF) brings together the finest student musicians from around Australia to perform together under the guidance of outstanding national and international conductors.  This is a biennial festival and in 2025, the 23rd ACSMF will be hosted by Westminster School in Adelaide for the fourth time since its instigation. Selected Scotch students have been accepted to attend.

The four-day festival will culminate in a gala concert with performances featuring the combined festival Concert Band, Orchestra and Choir.
