The reported hunting of Victorian wombats by Chinese high rollers has prompted an investigation into the animal's protection.

But the government can't say if anything has been done to immediately stop the wombat killings.

Under questioning from Greens MP Sam Hibbins on Thursday, Victorian Environment Minister Lily D'Ambrosio told parliament that she was alarmed by the recent reports and was waiting on a report from her department.

"I have instructed my department to undertake a full investigation into the allegations and reports of what appears to be some very, very disturbing practices," she told question time.
