When do registrations close? 11 December 2023 23:43 Updated April is the month of the mullet and we'd love you to sign up. You can register up any time until the end of April- it's never too late to grow that mullet! If you want to rock a mullet after April, you can of course do that as a separate fundraiser. Just contact us by email mullets@blackdog.org.au. Related articles Can I still take part if I already have a mullet? Do I need to shave off my mullet at the end of April? How do I create a team?
