Labor leader Rebecca White said the party would not be making any quick decisions until it is understood what the makeup of the Parliament would look like.

"We have to wait and first see who is elected on the recount," Ms White said.

There is speculation Franklin Labor MHA David O'Byrne will secure the role.

Mr Bacon confirmed his resignation on Thursday morning.

Ms White said Mr Bacon was spending Thursday in his electorate doing what he has done well for the past 10 years.

"He obviously has a lot of people he wants to speak to, catch up with and say goodbye to in some cases," she said.

Ms White said Mr Bacon did not attribute his resignation to any particular reason aside from it being the time for him to take on new challenges, however Greens leader Cassy O'Connor said Labor's ditching of its anti-pokies policy influenced Mr Bacon's choice to leave the Parliament.

"I've got no doubt that Labor walking away from a position of principle on poker machines has contributed to Scott Bacon's decision to leave," Ms O'Connor said.

"All through this year, Scott was looking pretty unhappy and disengaged with Parliament.

"That's a big loss to the Labor party when you have someone of significant integrity deciding they can't work within that framework anymore."
