Bio-logical at Duke of York Hotel

Did you know what undiagnosed STDs can cause mental disorders? Or which wild animals can be gay? Or anything about duck penises? Zoltan Illes, a former international biology teacher turned comedian, will answer all these questions and more in BIO-LOGICAL, playing at the Adelaide Fringe Festival in 2026.

BIO-LOGICAL is the debut stand-up show from Zoltan (real name) as he intertwines his nomadic, globe-trotting life as a clueless American with biology facts that were definitely not taught in school. Zoltan has lived in 16 countries and visited many more. Along the way, he’s loved cats, immersed himself in local cultures, waded in the dating pool, taught biology, and gotten old (did we mention the cats).

Zoltan has traded his classroom for a stage to not only entertain but to educate. He is an avid animal lover and volunteers at animal shelters when he can, in addition to donating to charitable causes (when he can afford to). BIO-LOGICAL will include virtual interactions, visual aids, and at the end of the show, animals available for adoption at the Animal Welfare League of South Australia will be displayed with an added bonus of a silly back story for each.

BIO-LOGICAL will debut at The Duke of York Hotel for Adelaide Fringe Festival, with a portion of ticket sales being donated to the Animal Welfare League of South Australia. Tickets on sale now.
