Greens Leader Christine Milne says some of the Labor leadership ''shenanigans'' of the past three years have rubbed off on the Greens, as her party assesses a nationwide swing against it of more than 3 per cent.

In Senator Milne's first election since taking over the leadership from Bob Brown, the Greens have recorded an ambiguous result, picking up a new senator in Victoria with Janet Rice but seeing a drop in its primary vote from 11.8 per cent in the 2010 election to about 8.4 per cent.

The party was able to celebrate the re-election of deputy leader Adam Bandt in the lower house seat of Melbourne and the expected re-election of South Australian senator Sarah Hanson-Young.

''This is a great victory for people in Melbourne and right across the country who want politics to be about reaching for new heights, not racing to the bottom,'' Mr Bandt said on Sunday.

Senator Milne said her party had been running against a ''tide'' of support for the ''conservatives'' during the campaign.
