“Under Singapore law I could not have become a citizen of Singapore by birth unless one of my parents was also an existing Singapore citizen. Singapore also does not allow dual citizenships for adults.

“Since the resignations from the Senate of Scott Ludlam and Larissa Waters a number of MPs have taken steps to clarify their status. The Greens want there to be a full audit of the status of members and senators.
