South Coast MP Shelley Hancock says she has been deluged with messages of support for Gladys Berejiklian after the Premier's appearance before the Independent Commission Against Corruption on Monday.
"I want to say thank you to all of the people who've contacted me and I'm sure have sent messages to her as well," Mrs Hancock said
"They're people from my electorate I don't even know, not traditional Liberal Party supporters but people who just said, 'We need Gladys, we need her to continue to lead this state.'"
Mrs Hancock said there was no reason for Ms Berejiklian to resign.
"I hope and pray that she's not even contemplating it."
She said the Premier had done nothing wrong in her dealings with disgraced former Wagga Wagga MP Daryl Maguire, whose activities are the focus of the ICAC inquiry.
"I'm not interested in what was going on in her relationship with him because that's her private and personal business. She didn't do anything to give favours towards Daryl Maguire."
Mrs Hancock said NSW could not afford to lose Ms Berejiklian, whose leadership through the bushfire crisis and COVID had been exemplary.
"While we might talented people in the NSW Liberal Party, I don't think anybody could hold a torch to Gladys Berejiklian. Not even close."
Mrs Hancock's comments echoed those of her close colleague, Kiama MP Gareth Ward.
"Every morning we saw this Premier at 8 o'clock during the COVID crisis. Every time there was an issue that our state confronted, be it bushfires, be it floods, she has been there," Mr Ward said.
He dismissed any suggestion the intercepted phone calls between Ms Berejiklian and Mr Maguire indicated wrongdoing or turning a blind eye to his activities.
"If that was a question then it would be a question before the ICAC and at no point has the corruption commission indicated that is a question they are pursuing after both a private deposition and now a public hearing involving the Premier," he said.
Both Mr Ward and Mrs Hancock brushed aside Opposition leader Jodi McKay's call for the Premier to resign.
"I think it's extraordinary that Labor would be attacking a premier for matters involving her personal life.
"Questions in relation to propriety are appropriately questions for an independent body," Mr Ward said.
