Around 200 wildfires were burning in four states, with New South Wales accounting for more than half of them, including 60 fires which are not contained.
Mr Morrison rejected calls to downsize Australia’s lucrative coal industry.
"I am not going to write off the jobs of thousands of Australians by walking away from traditional industries," he told Channel Seven.
Mr Morrison carried out interviews with several Australian television networks on Monday morning in the aftermath of his much criticised family holiday to Hawaii during the wildfires crisis.
"We all make decisions. You do as a parent, I do as a parent. We’ll seek to balance our work life responsibilities and we all try to get that right," Mr Morrison told Channel Seven.

More than three million hectares (7.4 million acres) of land has burned nationwide during a torrid past few months, with nine people killed and more than 900 homes destroyed.
Almost 800 homes have burned in New South Wales, which last week was paralysed by a seven-day state of emergency amid catastrophic conditions.
There will be desperately needed relief this week for New South Wales, with cooler conditions forecast.
However New South Wales Rural Fire Service commissioner Shane Fitzsimmons painted a bleak long-term picture.
He said: "We’ve got to keep in mind that we’re not expecting any rainfall to make any meaningful difference to these fires until January or February."
"That’s still a way to go. We’re still talking four to six weeks at best before we start to see a meaningful reprieve in the weather."
Mr Morrison’s coalition government won a surprise third term in May.
Among its pledges was to reduce greenhouse gas emissions by 26% to 28% by 2030 - a modest figure compared to the centre-left opposition’s pledge of 45%.
Mr Morrison has insisted Australia would meet its emission targets.
"I’m going to maintain the course of responsible management, responsibly addressing the changes of climate change and responsibly ensuring that we can grow our economy in what is a very tough climate at the moment," he said.
