It comes as much of the world watches the United Nations Climate Summit in New York -- an event Australia was not invited to speak at.

Australia was not been offered a speaking slot at the climate summit, as it's seen as a nation which supports the use of coal.

However, Mr Morrison says he will have his say on the issue at the UN General Assembly later in the week.
