The Greens will introduce legislation to abolish group voting tickets, as a number of micro-party candidates, with minute primary support, appear set to share the Senate balance of power.

The move comes as prime minister-elect Tony Abbott expressed in-principle support for reform of the Senate electoral process, which looks likely to deliver a Senate spot in Victoria that the Australian Motoring Enthusiast Party - which attracted just 0.51 per cent of the primary vote - and another spot in Western Australia to the Australian Sports Party - which received just 0.22 per cent of the primary vote.

''I think this is an issue and I think it will have to be addressed,'' Mr Abbott told Fairfax Radio on Monday, adding he wanted to wait until Parliament's committee on electoral matters completed its usual post-election inquiry.

In NSW, the Liberal Democratic Party is likely to win a Senate spot, largely because of its number one position on the ballot paper, and the similarity of its name to that of the Liberal Party.
