The man hoping to snatch the NSW premiership away from Dominic Perrottet says pork barrelling has found its way into the marrow of the government and the state needs a "fresh start".
Cheered on by a crowd of party faithful gathered in the battleground western Sydney seat of Penrith for Labor's unofficial campaign launch on Sunday, leader Chris Minns declared the coalition government's best days were behind it.
In a lengthy speech to about 300 party members including former premiers Bob Carr and Barrie Unsworth, Mr Minns said NSW was in the midst of a health crisis and its education system was in decline.
