THE expected election of Palmer United Party candidate Glenn "The Brick" Lazarus to the Senate will not be the only surprise awaiting the new Coalition Government.
Several of Prime Minister-elect Tony Abbott's key promises, including the scrapping of the carbon tax, will rely on delicate negotiation with a diverse Senate.
Among the candidates that he may need to appease could be Pauline Hanson and the likely return of South Australian Senators Sarah Hanson-Young and Nick Xenophon.
There is also a chance a second PUP candidate and a Victorian Motoring Enthusiasts Party candidate could make it via complex preference deals.
However, the final make-up of the Senate will not be known for some time.
