Greens MP Adam Bandt has a strong chance of retaining his seat and may not have to rely heavily on preference deals to do so, a new poll has found.

A Galaxy Poll of 400 constituents in the federal electorate of Melbourne, conducted in late July, revealed a very high satisfaction rate for the Greens deputy leader at 68 per cent.

The figure is up from a similar Galaxy survey in 2011, which showed a satisfaction rate of 55 per cent.

The recent poll also showed a primary vote of 48 per cent for the Greens in the Melbourne electorate (up from 36.2 per cent at the 2010 election), with 29 per cent for Labor and 21 per cent for the Liberals.
