The Gulbaru leaf-tailed gecko is thought to have a similar reproductive strategy as the broad-tailed gecko (Phyllurus platurus). They are inferred to mate at least until autumn and that females store sperm through the winter.
In early March 2001, two sexually mature male Gulbaru leaf-tailed geckos were collected. They were in peak reproductive condition with turgid testes and sperm present in the epididymis, inferred from opacity.
