as Prime Minister and as MPs were due to vote on a motion of no confidence against him. In response, from 20 April 2006, RAMSI forces were rapidly bolstered by a further 220 Australian troops. New Zealand sent a further rifle company and 30 police to increase its RAMSI contribution to around 160 troops and 67 police. The PPF comprised police officers from 15 Pacific nations: Australia, New Zealand, Papua New Guinea, Fiji, Republic of Marshall Islands, Palau, Federated States of Micronesia, Niue, Tonga, Samoa, Cook Islands, Vanuatu, Nauru, Kiribati and Tuvalu. 2013 military withdrawal On 1 July 2013, Australia, New Zealand, Tonga and Papua New Guinean forces began a "phased redeployment" from the Solomon Islands after it was assessed that the security situation in the country had stabilised. The last Australian troops returned to Australia on 1 August 2013. All Australian personnel and equipment were scheduled to be withdrawn by September 2013. After arriving on 24 July 2003, a total of 7,270 Australian personnel deployed during that country's support to RAMSI. Of these, 2,122 were Reserve personnel. Cost In the year of 2011–12, $43.5 million was spent on the Australian contribution to the RAMSI. In 2014 Jenny Hayward-Jones at the Lowy Institute estimated that Australian government spending on RAMSI as $2.6 billion in real terms to that date.
