Crossbenchers unite to stop 'right wing dirty deals'

Two progressive NSW crossbenchers are banding together in a bid to block "dirty backroom deals" by conservative opponents after the state's election.

Animal Justice MLC Emma Hurst and powerful crossbencher Alex Greenwich announced they would unite to block moves by Pauline Hanson's One Nation party and the Shooters, Fishers and Farmers after the March 25 poll.

"We are going to work together to prevent the far right wing agenda of One Nation and the Shooters and Fishers party from taking hold in NSW," Mr Greenwich said on Monday.

Legislation was introduced by One Nation MP Mark Latham during the last term of parliament that could have victimised transgender people, Mr Greenwich said.

"Mark Latham and One Nation has a really hardcore, anti-LGBTQI, particularly anti-trans, stance,'' he said.

"We've got to prevent that from happening."

Ms Hurst said the pair opposed various other policies proposed by conservative minor parties, including moves towards nuclear energy and a possible relaxation of gun laws to allow firearms in national parks.

"We really want to make sure that the incoming and government, whoever that is, works on a progressive agenda going forward," she said.

The pair has previously worked together to pass five private members bills, including legalising abortion and euthanasia and reforms to stop shelters culling animals. 

They are also working towards a ban on puppy farms.

Under their unity ticket, Mr Greenwich and Ms Hurst want a new ministry dedicated to animal welfare. 

In the event of a hung parliament the two MPs said they would seek an agreement with whomever forms government that no backroom deals would be done with minor parties.

Ms Hurst said their unity ticket was built on the idea of establishing trust with whomever formed government.

"That means not seeing them come and work with us to outlaw puppy farming, for example, and then going and making a dirty backroom deal to allow hunting in national parks," she said.

Shadow Treasurer Daniel Mookhey said NSW Labor would not do any deals with minor parties or independents in the event of a hung parliament.

"We're not doing any deals with any crossbencher for government," Mr Mookhey said on Monday.

Mr Greenwich said the opposition had been happy to make deals with him daily during the last term of government.

"Every single day of the last parliament, Labor was prepared to do a deal on legislation," Mr Greenwich said.
