Now it looks like another four MPs will face the High Court over their dual citizenship and the legality of holding office: The Australian, November 10, 2017, p. 1:

All this will apparently be solved by a round of by-elections. Many pollies want a referendum to get rid of section 44 (i) of the constitution.
Instead, how about politicians getting their act together and obeying the Constitution before standing? Section 44 (i) is perfectly clear, and there is no excuse for not obeying it.
Beyond this, we need to ask how the ineligibility of the various politicians affects votes on laws which have occurred. If someone was ineligible to hold office, they were also ineligible to vote. Consequently there needs to be an audit of how laws might be affected. Nothing has been said by the politicians about this, their only concern is how to sweep everything under the carpet.
