The state's eight police regions will be cut to five and districts reduced from 31 to 15 - a move that has .
Union spokesman Denis Sycz says the new regions are huge and is not sure if it will work.
"I've got concerns about the whole thing because there's no detail in how they're going to implement these changes," he said.

"There's a whole lot of concerns that we are going to be in negotiations with the service about and hopefully they'll listen to us and take those concerns on board."
The new structure will be in place by July 1.
