There will be two more NSW state by-elections in late 2017 in the seats of Blacktown, Cootamundra and Murray.
Former NSW opposition leader John Robertson resigned from parliament in August 2017. Labor should easily retain this seat.
Former Nationals minister Katrina Hodgkinson resigned from parliament in September 2017. The Nationals will likely retain this seat, but they will be challenged by the Shooters, Fishers and Farmers party.
Former Nationals deputy leader Adrian Piccoli resigned from parliament in September 2017. The Nationals would normally be strong favourites to hold Murray, but will face a strong challenge from the Shooters, Fishers and Farmers party.
