I'm praying the Libs refer him to high court to prove his citizenship , and can safely say he is hanging out for it as well , just to make you lightweights look even dumber than you already do

But Prime Minister Malcolm Turnbull is not sympathetic, telling Channel 9 the Greens have simply been sloppy.
"It is pretty amazing, isn't it, that you've had two out of nine Greens senators who didn't realise that they were citizens of another country. And it shows incredible sloppiness on their part. You know, when you nominate for parliament, there is actually a question. You've got to address that Section 44 question, you've got to tick the box and confirm that you're not a citizen of another country. So, it is ... it's extraordinary negligence on their part."
Under Section 44 of the constitution, dual citizens are not eligible to be elected to parliament.

British foreign secretary Boris Johnson renounced his United States citizenship last year, but only because he had to pay taxes there despite leaving as a five-year-old.
Opposition Leader Bill Shorten says his party does a proper vetting of each of its candidates before they can run for their seat.
"When you're a Labor candidate, you're required to confirm your citizenship and (that) you're not a citizen from another country. And we don't just rely on someone ticking a box. I understand, from speaking to the party administration, that, if you're born overseas, you have to record that fact and tell the party. If you've got a parent who's born overseas, then you have to show what steps you've taken."
