Police have released CCTV images of three women after the alleged possession and trade of the native animal at North Melbourne station on February 12, about 1pm.

The first woman is described as Caucasian, in her 50s, with blonde bob-length hair and wearing a black cardigan, blue shirt and grey pants.

The second woman is perceived to be Asian, in her 30s, with black hair in a high ponytail. She was wearing a grey cardigan and black-and-white printed dress.

The third woman is described as Caucasian, in her 20s, wearing a grey hoodie covering her face and red spotted pyjama pants.

The Victorian Department of Environment says it has intercepted hundreds of native species being illegally trafficked in recent months.

"We continue to pursue offenders in a bid to stop these cruel, illegal practices. Help us put an end to wildlife being trafficked, traded, and traumatised."
