With the Turnbull government's coffers looking healthier, aid groups hope some generosity can finally flow to the world poorest.

The government introduced a temporary freeze last year that would siphon $300 million from the aid budget from mid-2018.

This followed $11.3 billion of cuts since the coalition government came to power in 2013.

Aid spending now equates to about 22 cents in every $100 of gross national income, an historic low.

The peak aid body the Australian Council for International Development insists now that government revenue is up, there is an opportunity to start to repair the aid budget.

The Rohingya refugee crisis which has seen 700,000 people flee from Myanmar to Bangladesh, cyclone-hit Tonga and a deadly earthquake in Papua New Guinea are among disasters stretching resources of aid groups.

However, the call to boost aid could be wishful thinking, following speculation of another $400 million a year cut.

"Australia is increasingly seen as an unreliable development partner and a fair-weather friend," ACFID chief executive Marc Purcell told AAP.

Aid organisation Micah Australia is also pessimistic.

"Our lack of commitment to Australian aid coupled with an absence of any long-term vision for our role in the region means that our soft power is waning, along with our reputation," spokesman Matt Darvas said.

"When will our government believe we have enough so we can start being generous again?"

Meanwhile, the Department of Foreign Affairs and Trade released its aid performance report, which showed some aid programs in the Pacific were struggling to meet objectives.

At least 35 per cent of program objectives were considered "at risk" and three per cent off track.
