What’s Happening?
Rockhampton Zoo has announced the passing of Cassius, its beloved male chimpanzee, on Thursday, 17 April 2025. Cassius, also known affectionately as “Cassie,” passed away peacefully after a rapid health decline earlier in the week.
Why It Matters
Cassius wasn’t just a zoo resident—he was family to the Rockhampton community. For nearly four decades, he formed a deep emotional bond with staff, visitors, and fellow troop members. His passing marks the end of an era for the Zoo and the broader region.
“Cassius had the best possible care, and if there’s any solace to be found, it’s that he wasn’t alone when he passed away,” said Rockhampton Zoo Director Liz Bellward.
“Zoo-goers have loved Cassius since day one… his warmth and engagement made him truly unforgettable,” she added.
Local Impact
The loss of Cassie has left a deep impact on Rockhampton Zoo staff and long-time visitors alike. His calm, friendly presence enriched the lives of thousands. The Zoo will host a public memorial in the coming week to allow the community to say goodbye.
Cr Cherie Rutherford, Parks, Sport and Public Spaces Councillor, expressed the collective grief:
“This news has shattered our entire zoo family and the community who have loved Cassius for decades.”
She continued, “We hoped Cassius had more time… however for his comfort and welfare, we had to say goodbye as we loved him too much to let him suffer.”
By the Numbers
-
53 years: Cassius was the oldest male chimpanzee in Australasia.

Zoom In
Cassius had been battling arthritis and dementia in recent months. The Zoo had shared an update in March detailing the team’s efforts to manage his condition. Despite the devoted care from veterinary teams, the decision to euthanise him was made to prevent further suffering.
“Cassius lived a long, remarkable life… he was a strong yet gentle member of the troop,” said Ms Bellward.
“He was always accepting of new members. The troop will undoubtedly feel this loss. We will be closely observing them to support their wellbeing,” she added.
Zoom Out
Cassius’ life represents the evolving bond between animals in care and the communities that support them. For Rockhampton, Cassie became a generational figure—someone locals grew up visiting. His death invites reflection on wildlife care, ethics, and the emotional role animals play in public institutions.
What To Look For Next?
Rockhampton Zoo will share memorial details on its official Facebook page in the coming days. The public is encouraged to attend and celebrate the life of a truly unforgettable chimpanzee.
