The Australian Competition and Consumer Commission says it's received about 150 reports of scammers using the threat of deportation to extort money.
The Commission says the scammers are targeting both Australian residents and those temporarily in the country on various visas, by impersonating government officials, demanding up-front fees of around $1000.

Deputy Chair Delia Rickard told Van Nguyen a high proportion of those targeted have been people from India and Pakistan.
