The alligator is among 23 reptiles – including lizards and dragons – taken from the Australian Reptile Park on the Central Coast on Sunday night.
Police were called to the park in Somersby at about 11pm (AEST) following reports of a break and enter.
There are concerns for the reptiles as some are sensitive and require high maintenance.
Police say without proper care there is a significant risk that the creatures won’t survive.
