Former Labor prime minister Julia Gillard has appeared at a concert on the eve of the G20 summit in Germany to appeal for more funding for education in developing nations.
Ms Gillard, who chairs the Global Partnership for Education, went on stage at the Global Citizen Festival in Hamburg with Malawi student Wongani Nyirenda.
She and singer Rhianna in January visited Malawi, where the GPE has provided $US45 million for better trained teachers, classrooms, toilets and teaching materials in 800 schools.
"We urgently need more funds if we are going to help many more developing countries to build strong education systems so that every child can get a good education," she said.
The GPE is holding a conference in early 2018 to raise $US3.1 billion to fund its work for the next three years, helping 870 million children across 89 countries.
"We are asking you as global citizens to tell your governments to fund education and shape the future," Ms Gillard said.
The concert involved artists including Coldplay, Shakira and Pharrell Williams.
