More than 12 reptiles were seized from a Wodonga house last month after a tip off from the public.
The haul by the Department of Environment, Land, Water and Planning included five pythons, six blue-tongue lizards and a bearded dragon.
There was also frozen dead wildlife found at the property.
DELWP forest and wildlife officer Andrew Dean found the animals during the execution of a search warrant.

"We received a tip off that the owner may be in possession of a high-risk invasive snake," he said.
"The owner was not in possession of a high-risk invasive snake, however, they were keeping native wildlife without a licence, which is an offence under the Wildlife Act 1975.
"We are now reminding people that if they own protected native wildlife they must have a valid licence.
"These regulations allow us to monitor the number and type of wildlife being kept legally across the region."
