Brisbane community radio station 4ZZZ already secured impressive celebrations for its 50th anniversary, but it turns out that honouring the milestone will continue until the end of the year.

This year, 4ZZZ will move its annual music countdown, the Hot 100, to coincide with its 50th birthday. So, on Sunday, 7 December, the radio station will celebrate the “spiciest, sweatiest” songs of the year, as voted by its listeners.

4ZZZ will keep the focus on the broadcast for the upcoming anniversary Hot 100, with more information set to be announced soon.

Voting for the countdown opened on Friday (7 November) and closes at midnight on Sunday, 30 November, with strictly one vote per person allowed. Songs released between 1 November 2024 and 31 October 2025 are eligible to feature in the Hot 100. To have your say, head to the 4ZZZ website.

If you’re a 4ZZZ subscriber, you’ll receive extra perks for the Hot 100 voting, with double weight in votes and save your shortlist and edit it another time.

A notice about this year’s celebration reads, “The Hot 100 has been a mainstay of 4ZZZ’s identity for decades, beginning in 1976 (one of the first countdowns in the country!)

“For one year only, we’re mixing up the date of our annual music countdown to coincide with our milestone birthday. On December 7th, we’re celebrating the 🔥SPICIEST, SWEATIEST TRACKS🔥 of the year– as voted by you, the listener! The birthday celebrations have been a mammoth project, and we couldn’t think of a better way to bring it home than a bit of good old-fashioned democracy.”

In late October, 4ZZZ and local acts commemorated the community radio station by holding an epic concert at the Roma Street Parklands.

Across two stages, clash-free live music took over for 4ZZZ - ZED50: A Market Day Celebration of 50 Years of 4ZZZ Radio. Acts who performed included The Saints 73-78, Regurgitator, Tropical Fuck Storm, Full Flower Moon Band, Screamfeeder, Platonic Sex, Velociraptor, and many others.

4ZZZ Chairperson Ruth Gardner said of the milestone anniversary and its celebrations: “This is more than a birthday—it’s a tribute to everyone who’s ever tuned in, turned up, or taken part.”
