Over the next few days, the Australian government tried in vain to persuade the Papua New Guinean government not to proceed with the mercenary deal. On the night of 16 March 1997, the revolt began. PNGDF soldiers were approached by leaders of the NGO Melanesian Solidarity (MELSOL). Jonathan O'ata and Peti Lafanama wanted to consolidate a military-NGO civil protest against the Chan-Haiveta decision to engage the Sandline mercenaries. By the time the night was over, the entire band of Sandline mercenaries had been disarmed and arrested. Prime Minister Chan did not find out until the next morning. That morning, Singirok accused Chan, Ijape, and Haiveta of corruption, and gave them 48 hours to resign. He also fiercely denied allegations that he was aiming to take power himself. Chan refused to resign, and the same day, sacked Singirok as Commander of the PNGDF, replacing him with controversial Colonel Alfred Aikung. The NGOs activated a nationwide protest in support of General Singirok.
