We know they are kangaroo faeces because the person holding the video camera picks up a brown pellet, examines it, and says: ''This is kangaroo poo. Yum yum.''Mr Muir, who will likely become a federal senator next July despite winning a minuscule percentage of votes, looked sheepish when asked about the faeces fight.

"Before all this come around I was just an ordinary Australian," Mr Muir told Seven News.

"If you've ever spent much time in the bush, you go out there and you discover there is poo everywhere."

In another scene in the home video, Mr Muir perches on the roof of a four-wheel drive and spits in the direction of the camera. At yet another point, the likely senator pulls down a bearded man's pants. Later in the video, he strikes the man with jousting sticks.

"Well, people play," Mr Muir explained to Seven News. "My brother and myself were having a bit of a wrestle that day and you just end up on the ground."Mr Muir, whose party's core values include "mateship", lower taxation and "taking pride in our vehicles", is among a curious assortment of likely senators who have benefited from tightly swapped preferences between minor parties.
