Barnaby Joyce is fighting to keep his hold on the Nationals' leadership as a new poll shows three in five Australian voters - or two in five Coalition voters - see him as an electoral weakness.

Joyce's future as leader of the junior Coalition party will be decided at a party room meeting at 10am on Monday, with rival candidates David Littleproud and Darren Chester making the case for a refresh in the wake of the Coalition's electoral rout.
