The AEC puts out a guide for candidates to parliament.
The most important part of it is here
Pretty obvious from that form that the candidate has to be qualified under the constitution. If you sign the form saying you are eligible under the constitution and then you aren't, I believe that becomes fraud. And when the profits from that fraud are a cushy job, marvellous pension scheme,$3000 a week base pay,$279 a night living away from home allowance, $170 a day meal allowance and the bike ride scam or the Roman holiday scam some politicians get up to. Massive fraud.
