The government will start chasing students with unpaid student loans if they move overseas.

From July 2017, people living overseas and earning more than the current $53,345 threshold will have to start paying back their HELP student loans.

From 2016, students intending to leave Australia for more than six months will also be required to register with the Australian Taxation Office.

Those already living overseas will be required to register with the ATO before July 2017.

The government hopes to reap back $140 million over the next decade by chasing students who avoid detection.

The measure comes after Professor Bruce Chapman of the Australian National University argued that students should be asked to pay back at least $2,000 of their outstanding student loan debt if they travel or move to another country for more than six months.

“If people can afford to go to Europe or the US and travel around or work then I think they can afford to make this sort of repayment,” he told The Australian in March.

Many avoided paying back fees by not filing a tax return in Australia while they were overseas, thereby going undetected by the ATO.

The value of outstanding federal student loans is $30.6 billion.
