An attempt to spill the leadership of NSW Premier Gladys Berejiklian has been called off by three rebel MPs.

Backbenchers Tanya Davies, Lou Amato and Matthew Mason-Cox planned to move a spill against the Premier at a party room meeting this morning due to their anger over the handling of a bill to decriminalise abortion.

Just before 8:00am, Ms Davies released a statement saying the group had received confirmation that further concessions would be forthcoming in relation to the bill so the decision was made to withdraw the spill motion.

Ms Davies said she has advised the Premier of the decision.

The rebel MPs released a statement last night claiming they had been "bewildered by the lack of regard for proper parliamentary process" and the failure to allow members meaningful consultation with their local communities.

Shortly after the motion was abandoned, Deputy Premier John Barilaro told Sky News the Liberal Party would move on and denied there was an internal crisis.

"Let's get over today, get over a few of the egos that got in the way overnight," he said.

"One of the things I know about Gladys is she has the ability to bring people back into the fold."

Mr Barilaro said he tried to warn his colleagues last night about their "dumb decision", but he was positive Ms Berejiklian would be able to "forgive".

The Nationals leader said he was disappointed with the trio as they knew negotiations regarding the amendments were still underway.

"These guys have jumped the gun … the journey hadn't ended," he said.

Independent Alex Greenwich introduced the bill to decriminalise abortion last month and it passed the Lower House 59 to 31, with Ms Berejiklian voting in its favour.

It has ignited passionate public debate and a number of fiery protests outside the gates of Parliament House by religious groups.

It also revealed division within the Liberal Party, with Ms Davies initially threatening to defect to the crossbench if the bill was not amended.

Former Nationals Leader Barnaby Joyce told ABC Radio National the spill motion was never a personal attack on Ms Berejiklian.

"We're not arguing against Gladys Berejiklian, we're campaigning against the processes," he said.

He said he had no problem with the decriminalisation of abortion but was against "leaving a baby in the corner of the room to die" and was opposed to the bill in its current form.
