MPs who are found to be dual citizens, but fail to out themselves in the near future, could be forced to repay their wages, according to a report in The Australian Financial Review. Citing unnamed sources, the report says the government is now considering refusing to grant a waiver to MPs found to have been ineligible to run for office at the time of their election. Those booted so far have been excused from repaying the wages, which, in some cases, run well over $1 million.

The latest name in the section 44 mix is Energy Minister Josh Frydenberg, whose mother was born in Hungary but fled the Holocaust before arriving in Australia as a refugee. On ABC radio this morning, Frydenberg said he was born in Australia to two Australian citizens and that it would be "absolutely absurd" if he had inherited Hungarian citizenship from his mother, who he said arrived in Australia stateless.
