Brash was a committed philanthropist who, in the mid-1980s, established the Brash Foundation, which eventually morphed, with other partners, into the Soundhouse Music Alliance. This was a not-for-profit organisation overseeing and promoting multimedia music making and education for teachers and students. The Soundhouse offers teachers and young people the opportunity to get exposure to the latest music technology, and to use this to compose and record their own music, either alone or in collaboration. The organisation has now also established branches in New Zealand, South Africa and Ireland, as well as numerous sites around Australia.
