The 2025 campaign marks a bold new creative chapter for AusMusic T-Shirt Day, developed in partnership between Support Act and Mushroom Creative House. Support Act CEO, Clive Miller, says: “This year, it feels like AMTD has exploded forward. Support Act Campaign Director – AusMusic T-Shirt Day, Rachel Campbell says: “In shaping this year’s campaign, I knew we had to get to the heart of why AusMusic T-Shirt Day matters. Australian music workers show up 365 days a year, and AusMusic T-Shirt Day is our chance to show up for them, in recognition, in joy, and in celebration, so that Support Act can keep showing up when times get tough. AusMusic T-Shirt Day is proudly supported by founding partners triple j and ARIA, and supporting partners Mushroom Creative House, Love Police and American Apparel.
