Mr Morrison told a press conference this afternoon that he had confirmed his attendance at the UN climate summit, which begins on November 1, overnight.
The prime minister had faced criticism for having not confirmed his attendance earlier, previously flagging further COVID-19 quarantine as a roadblock.
"The government will be finalising its position for me to take to the summit, prior to my departure, over the next fortnight," he said.
"Net zero was an outcome that I outlined at the beginning of this year consistent with our Paris commitments."
But hitting net zero was not the government's only goal, he said.
"The global changes that are happening in our economy as a result of the response to climate change have a real impact and they will have a real impact here in Australia," he said.
"It is not just about hitting net zero.
"That's an important environmental goal but what's important is that Australia's economy goes from strength to strength and the livelihoods and the lives of Australians, particularly in rural and regional areas, are able to go forward with hope and with confidence."
Australia has pledged to reduce its greenhouse gas emissions by 26 per cent to 28 per cent by 2030, from 2005 levels, a commitment that sits well below those made by the United States, European Union and United Kingdom, among other developed nations.
The government in December last year technically "updated" its NDC, as it was obliged to do by the Paris Agreement before a July 31 deadline, but it did not actually increase its target to cut emissions.
The point of the deadline was for countries to raise their climate ambitions.
Australia's current pledges do not even put it on track to meet the requirements to keep global warming within 2 degrees Celsius, let alone 1.5, according to Climate Action Tracker, a group that monitors climate policies around the world.
The watchdog said that if the whole world followed Australia's policies, temperatures would rise by between 2 and 3 degrees.
