Mandatory quotas have serious flaws in a system of single-member electorates.
Reserving quotas of seats attempts to make parliaments more representative in one respect by making them less representative in another. But there is no guarantee that those seats reserved for females will be taken off the non-performing males. The real problem is largely the single-member system used for all lower houses on mainland Australia. Having only one MP for each electorate means each party runs only one candidate in each electorate. Thus, mandating that there must be a female ALP candidate in certain electorates inevitably will mean that there is no male ALP candidate in those electorates - even if ALP voters and party members therein would prefer a particular male on an individual basis.
