I want to know how the department can cancel my partner's Australian permanent residency. My partner was a secondary applicant in my Permanent Residency file. After getting the Permanent Residency with me, he went to India and get married another girl. I was used by him just to get Australian permanent residency. How can his Permanent Residency be cancelled under Immigration Law? Now I also want to get a divorce as he is not a trustworthy person. Regards.
