In between are meetings, briefings, media conferences, multiple events and pressing matters of state.

He eats "on the run" and uses travel time to stay on top of his reading.

Exercise is entirely dependent on staff finding space in his all-important and jam-packed daily diary.

Life is currently "hectic" for the state Member for Dubbo who has again assumed the duties of Acting Premier of NSW.

It is the sixth time that the former country cop has stepped into the shoes of Mike Baird since becoming the Leader of the NSW Nationals and Deputy Premier in October 2014.

His current stint at the top of the political pile will be the longest with Mr Baird off on holidays for about two weeks.

Mr Grant held the fort last Christmas when interstate bushfires required his attention.

Next week he will tour regions hit by flooding after returning to Dubbo to see constituents and family.

Currently in Sydney, he reports of being "homesick" but honoured to be serving the state of NSW.

"The day you don't appreciate the job or you don't see it as a privilege is the day you should give it up," he told the Daily Liberal.

Floods, drug-taking at festivals and test cricket have been on Mr Grant's agenda this week, providing him with the opportunity to mingle with "amazing people" including McGrath breast care nurses, cancer patients and Prime Minister Malcolm Turnbull.

But as he holds the reins of the state, Mr Grant insists he is "first and foremost" the Member for Dubbo.

"I'd be happy to be home every day of the week but it's just not possible and ultimately it would not produce the best outcomes for Dubbo," he said.

"I've got to be where decisions are being made so Dubbo benefits."

Mr Grant said the problem-solving, listening and communication skills he developed as a police officer had helped in "stepping up to another level of responsibility".

He is an advocate of explaining the why-and-wherefore of government decision-making.

"Most people when they have things explained to them, more often than not will usually go with you, even though they don't like what you're doing," he said.

The two-term politician, husband and father, considers the people he encounters to be the "best part" of his current job and press conferences the worst.

"You're there in front of the world pretty much," he said.

"You've got to focus on not making a boo-boo and I've been known to make a couple."
