"The feedback we've had ... has helped us identify where the gaps are right now, and how we can get support out the door quickly to where it's needed," Morrison said in a statement. The government had recommended the governor-general declare the floods a national emergency, he said.
Morrison, who is trailing in polls ahead of a federal election before May, on Wednesday made private visits to a flooded farm, the office of an emergency crew and also met with a person who lost their home, media reports said.
Television footage showed some people gathered in front of an emergency operations centre, where Morrison was due to visit, yelling "the water is rising, no more compromising" and "fossil fuel floods". Morrison's conservative government late last year adopted a net zero carbon emissions target by 2050, but climate activists are demanding more aggressive action.
