They will not have too trawl to hard. A quick computer search will tell them all they have to know. Refunding everyone that has applied will be fun though as everyone whom has applied after the 20th Apr until the new rules (if passed) is technically able to apply. I think the rules will change but not in the present format, but what that will be, will be another issue. Besides, with the current MP/Senator eligibility wrangle that is going on, I think that the proposed changes are going to be put on the back burner as each party gets its own little ducks in a row. Hopefully the Senate review committee will not support the proposed changes in terms of (time) eligibility.
