Funnel-web poison is needed to make the anti-venom which is used to treat spider bite victims. Without the anti-venom, victims may die within the hour.
Julie Mendezona, who works at the park, says venom stocks are worryingly low.
She is urging anyone who catches a funnel-web to bring it in.
“Usually we are the ones saying to people, ‘if you see a dangerous animal, leave it alone and then it will leave you alone, and you won’t have any run-ins’,” she said.
