Paramedics and the NSW government will appear at the industrial tribunal in the hopes of resolving a long-running stoush over pay.

The bitter dispute has plagued the Minns government for more than eight months as paramedics point to higher salaries offered to their colleagues in the ACT, Queensland and Victoria.

The Health Services Union and government officials will meet at a hearing before the state’s Industrial Relations Commission on Monday afternoon.

The union rejected a pay offer last week that would have lifted salaries by an average of 19 per cent.

The complex four-year offer did not match base pay for Queensland paramedics and would leave NSW workers short changed, the union said.

If a deal isn’t struck by the end of the year, 2100 paramedics have threatened to allow their professional registrations to lapse on January 1.

This means paramedics would be legally unable to attend triple zero calls from new year’s day if they don’t apply for renewal.

Health Minister Ryan Park warned the state’s triple zero emergency system could collapse on one of the busiest nights of the year if the matter is not resolved.

“We’ve made it clear that we are happy to continue the discussion around refining that (offer) and what that might look like,” he said on Monday.

“But we always have to understand that we are working, just like any government and just like any family is, in a budgetary challenging position.”
