But Mr Fitzsimmons praised the role the Australian Defence Force (ADF) had played in the fire fighting effort since late last year.
"We have been working extremely closely with the ADF and the Commonwealth over the recent months,particularly during the worst of these conditions,"Ms Fitzsimmons said.
"The partnership and arrangement has been better than ever before in the history of this state that I can recall over my decades."

Ms Berejiklian confirmed that Mr Morrison called her before he made his announcement.
"The Prime Minister contacted me directly shortly before details were released and I was pleased to take the call and welcomed the additional support,"Ms Berejiklian said.
Mr Fitzsimmons said Sunday's weather would bring more mild conditions giving some reprieve but he urged people not be complacent as areas of southern NSW still had significant threats.
"It will be a psychological reprieve for many,but not the relief we're looking for the terms of putting these fires out,"Mr Fitzsimmons said.
"We are getting reports that the property losses,the damage and destruction,is likely to be numbering in the hundreds as a result of yesterday's fire activity and fire spread."
Mr Fitzsimmons said Saturday was"a very difficult day".
"Once again,can I just commend and praise the extraordinary effort of our men and women,whether they're paid or volunteers,the effort yesterday was quite remarkable,"he said.

"It goes down as the second busiest and most challenging day in terms of the number of concurrent fires we had burning at the emergency warning alert level,we got to 13 or 14 at any given point,second only to what we saw a couple of months ago,where 17 concurrent fires were burning.
"It was an awful day yesterday."
Sydney sweltered through what is believed to be its hottest day on record on Saturday,with the mercury at Penrith soaring to 48.9 degrees.
The Bureau of Meteorology is yet to verify it as a weather record,but records show the previous hottest temperature had been recorded as 47.8 degrees in 1939 at a now-defunct weather station in Richmond.
