I’m Sean Costello, an integrated media producer, video editor, and musician based in Sydney. Over more than two decades I’ve delivered high-impact audio-visual content across live events, broadcast, advertising, and the arts. I own and direct Big Day Media, collaborating with advertising agencies, event producers, councils, arts organisations, and national broadcasters to bring ideas to life from concept through post-production and on-site delivery. With 30+ years as a performing musician—featuring composition and sound design—I bring a storyteller’s instinct and sonic craft to every project. This blend of creativity and hands-on production know-how helps teams push boundaries and craft work that resonates with audiences.…I’m Sean Costello, an integrated media producer, video editor, and musician based in Sydney.
