“PNG is a dangerous place for pregnant women and their newborns, not only because of widespread poverty but because of the extremely high incidence of domestic violence,” it said.

A separate government review of PNG’s national health plan published last year found the health sector had an “overall decline in performance over the last five years”.

Nigel Spence, the chief executive of ChildFund Australia, said it is disturbing that some indicators suggest the health challenges facing women in PNG are getting worse.

"It remains an unrecognised crisis that maternal health in PNG is at such a low point," he said.

"No woman should die giving birth. Yet in a country just 160 kilometres north of Australia, women are losing their lives every day during childbirth due to unsafe conditions and causes that are completely preventable."

Mr Spence said greater support needs to reach the local and village level, where most women in PNG give birth.

"The loss of life is at an appalling level," he said.

ChildFund's report, called National Health Crisis: Maternal Deaths in Papua New Guinea, says the lifetime risk of dying during childbirth is 1 in 120 in PNG compared to 1 in 8700 in Australia. Also, a newborn in PNG is 10 times more likely to die in the first month of life than an Australian newborn.

PNG is the largest recipient of Australian overseas aid and improving the health system has been a key aim of that support.

Even though this month’s federal budget revealed a $141 million cut to the overseas aid budget over the next four years, Australia’s contribution to PNG will increase from $541 million this financial year to $572 million in 2018-19.

Mr Spence said past aid spending by both governments and non-government organisations in PNG had "not always had the achieved the desired results".

But he said Australia has the means and the technology to do much more.

"This is our nearest neighbour and by any measure it’s an injustice that women not far from our shores are experiencing such risk when they are giving birth."
