When world leaders next meet to assess progress towards the Millennium Development Goals (MDGs) they will rely, in part, on a snapshot of global impoverishment to be generated in Australia next week.

Representatives of more than 300 non-governmental organisations (NGOs), those aid groups and charities working "at the coalface" in the poorest of nations, will gather in Melbourne for talks and to draft a communique for the United Nations (UN).

Professor Phil Batterham said the groups' message to the UN would be that global progress towards the MDGs was mixed, and now was not the time for affluent nations to tighten their belts on foreign aid.

"To be quite honest, we've got to convince world leaders to hold the line," said Prof Batterham, from the University of Melbourne and Convenor of the 63rd Annual UN DPI/NGO Conference.

"It would be very easy for world leaders to flinch at this point in time, with the global financial crisis still rattling around much of the world ... We've got to keep them on board."

The three-day conference will attract around 1500 delegates from 70 countries and it opens on Monday with a speech from UN Secretary General Ban Ki-moon.

It comes just ahead of a UN summit starting in New York on September 20 that will assess global progress towards the MDGs - ambitious targets for reducing poverty around the world by 2015.

The view of the NGOs should also inform discussions at another major meeting in October, when UN donor countries will be asked to replenish a $US30 billion fund used to combat HIV, malaria and tuberculosis.

"We're hoping this will allow the voices of the NGO community, who work very much at the coalface in global health and development, to be heard on what needs to happen," Prof Batterham said.

"There's certainly a lot more work to be done and a lot more for the world leaders to talk about."

Prof Batterham also said the push to improve living standards in the world's poorest nations was as much about promoting stability as it was about combating disease.

While there was a cost of taking action, Australians should also consider the costs that flow from not doing enough, he said.

What is the cost of poverty? It is enormous," Prof Batterham said.

"We don't just pay through the obvious costs of (combating) AIDS, SARS and swine flu - we pay the cost because wars start and people jump in boats and emigrate because of poverty.

"The world is a better place if people and Asia and Africa are healthier than they are now."

Melbourne is the fourth city to host the conference, after it was held for 60 years in New York before heading to Paris and then Mexico.
