"No decision's been made," Dutton told Radio 2GB. "So they'll (the Dragons) have to answer questions about their approach."
Dutton said that, generally, if a non-Australian citizen had broken the law - be it assault, theft or rape - they can "expect to have their visa cancelled and sent back to their country of origin".
"We take into account considerations around Australian-born children, how long people have been here - all of that is available to weigh up against the severity of the crimes being committed."
The NRL said its decision to give Packer the all-clear was made independent of the federal government and solely based on whether he was considered fit to return to first grade.
"Any determination by the federal government will be made separately and that's a matter for them," an NRL spokesman told AAP. "We're only in charge of our own business and our own competition. Given the time out he's had and the way he's responded to that, we think it's appropriate he be allowed to return."
The Dragons have been contacted for comment.
