OK, so I'm just checking the electoral nomination process, and to stand for the Senate, you must provide a deposit of $1,000. You only get it back if you are elected, or if you get at least 4% of the first preference vote (to put this in context, last time I checked, nobody outside the three major parties got over 4% in VIC - yes, I think it's fair to say the Greens are now a third major party).
The reason I checked this is because of Glenn Shea, who stood as an ungrouped candidate in VIC and made absolutely NO information available. On the AEC website, his official candidate info gave his employment as "Koori youth worker", but no contact details (unlike every other candidate), and Googling produced almost no information, except a couple of news articles about a play he wrote (or somebody with the same name, who knows!), and a board game he created (or again, somebody with the same name). Nobody could find anything definitive on him. He appeared to release no information whatsoever.
Why on earth would you go and blow $1,000 and not even try to encourage somebody to vote for you? Last time I checked the AEC, he received the staggering total of 165 first preference votes statewide.
