London: Australia has turned up empty handed to a major international conference which has pledged more than a quarter of a billion of dollars for women affected by President Donald Trump's reinstatement of the "global gag rule", which has stripped international non-government organisations that provide abortion services, advice or referrals of US funding.

The order was one of Mr Trump's first actions as President and restricts US funding not only for family planning organisations but to other health service providers. It is estimated it will leave aid organisations short of $US600 million (or around $790 million), which campaigners say will put millions of women's lives at risk.

To make up for the shortfall, the Dutch Minister for Foreign Trade and Development Cooperation, Lilianne Ploumen, established the She Decides movement to raise money from both through private sources and other governments.

Ministers from Belguim, the Netherlands, Sweden and Denmark organised today's pledging conference. It raised €181 million or around $251 million.
