Some unusual political parties that hold the balance of in the Australian Senate

Some of these parties won seats with as little as 0.2 percent of the vote because of the strange way that parties can swap unused votes.  From UK Telegraph:

Ricky Muir, Australian Motoring Enthusiasts Party 

Muir, 32, supports four-wheel "bush bashing" – or driving off-road in the outback. He posted an online video, which he has now removed, of himself throwing "kangaroo poo" in a garden. "What's the big deal?" said his spokesman. He also suggested on twitter that George W Bush was responsible for the September 11 attacks. 

David Leyonhjelm, Liberal Democrats 

A pro-gun libertarian, Leyonhjelm appears to have won in part because his party appeared first on the lengthy 3.3-foot Senate ticket and because some voters may have thought he represented Tony Abbott's Liberal party. "Looks like I'm going to be the senator for the donkeys," he said, referring to the throwaway votes – or donkey votes – which are likely to get him elected. 

Jacqui Lambie, Palmer United PartyA former soldier who opposes same sex marriage, she said she joined mining tycoon Clive Palmer's party because "I just didn't have the money like the big players did for advertising". 

Wayne Dropulich, Australian Sports Party 

A former member of Australia's gridiron – or American football – team, Dropulich, a civil engineer, said he and some friends came up with the idea for the party several months ago. His party's slogan was: "Are you more interested in sports than politics?" 

Glenn Lazarus, Palmer United Party 

A former Australian rugby league forward, he is known throughout the nation as "the brick with eyes". He once posed naked with a brick to promote a brick company. 

Bob Day, Family First 

Day's Bible-based party supports family values and housing affordability.The party had a previous Senator, Steve Fielding, who was famous for his outlandish stunts, including turning up to Parliament dressed as a beer bottle to promote recycling.
