Election analysts look set to be flying relatively blind into the state election, with no new voting intentions polling expected from key pollster EMRS before Saturday.
EMRS managing director Adam Perkins said the pollster's usual cycle for its omnibus polling would have fallen just after election day.
It did not intend to bring it forward.
Elections analyst Kevin Bonham said he would refuse to forecast results without polling data.
"I'm aware there's loads of internal party polling going on, but I am not aware of anyone at this stage who is doing any kind of public poll," Dr Bonham said.
"It's a parlous situation.
We have parties making claims about the likely result of the election and putting arguments to voters that they should vote a certain way based on assumptions of what might happen.
"(Without data) we don't have any way of commenting on whether these comments are likely to be true."
