The Senate represents the States. Each State gets 12 senators, each Territory two, and every three years in regular elections half of them are elected to serve a six year term.
Conservative Party leader Cory Bernardi says it's important more Conservative Party senators are elected so that they can help whichever party forms government in the lower house shape better, common sense legislation.
Without the Senate, theoretically a state with a large population like New South Wales or Victoria could force legislation through federal parliament which would disadvantage the smaller states.
Senator Bernardi's told Kel Richards on Sydney radio station 2CH, it wouldn't be healthy for Australian politics if Canberra went the way of Queensland and the territories and adopted a unicameral or one chamber parliament.
