The pact, signed in October 2025, is [Papua New Guinea's](/ja/entity/papua-new-guinea) first-ever formal defence alliance and Australia's first mutual defence treaty in more than 70 years. It covers intelligence sharing, logistics and training, and includes a pathway for up to 10,000 Papua New Guineans to join the Australian Defence Force. The Australian government has described it as a major "breakthrough in the Pacific." China and a former PNG Defence Force commander have criticised the pact for infringing PNG's independence and sovereignty. Marape said the agreement would boost PNG's security capabilities while maintaining national sovereignty. Albanese separately hosted Marape alongside the leaders of Samoa and Tonga at the State of Origin grand final in Brisbane that evening. ## The split PINA and Pacific island regional coverage foreground the sovereignty criticism from China and within PNG, giving the critique real estate alongside the official framing. Australian outlets treat the pact as an unambiguous bilateral achievement. The South Asian diaspora press in Australia pairs the defence treaty with a A$250 million rugby league investment, presenting both as expressions of Australian Pacific engagement, a framing that does not appear in the Pacific island press. ## By the numbers - 10,000, the maximum number of Papua New Guineans who can join the Australian Defence Force under the pact - 70+, the number of years since Australia last signed a mutual defence treaty - October 2025, when the Pukpuk Treaty was originally signed before entry into force ## Why it matters The Pukpuk Treaty formalises a deep security relationship that gives Australia first-partner status in Papua New Guinea at a time of intensifying Chinese engagement across the Pacific. The ADF pathway is an unusually deep integration provision for a bilateral defence pact, giving the alliance institutional weight beyond the paper commitment. PNG is strategically significant as the largest Pacific island country and sits directly on Australia's northern approaches. China's criticism signals Beijing reads the treaty as part of an emerging Pacific security architecture directed at limiting its regional influence. ## What to watch - Whether China escalates its diplomatic response to Papua New Guinea or applies economic pressure over the treaty - How many Papua New Guineans enlist in the ADF and whether the pathway develops real institutional weight over time - Whether other Pacific states consider similar bilateral defence arrangements with Australia - PNG domestic political reaction, particularly from Defence Force veterans and opposition figures who oppose the sovereignty terms ## Regional takes (batched by bias / lens) ### Pacific regional wire; frames the treaty as PNG's first-ever defence alliance, emphasising the ADF pathway and noting China's sovereignty criticism - **PINA (Pacific Islands News Association)** (Pacific, en) — PINA reports the Pukpuk Treaty entered into force on July 9 as Marape and Albanese met in Brisbane. The wire notes it is PNG's first-ever defence alliance, covers the ADF pathway for up to 10,000 Papua New Guineans, and flags that China and a former PNG Defence Force commander have criticised the pact as infringing PNG's sovereignty. > "The Papua New Guinea-Australia Mutual Defence Treaty, known as the Pukpuk Treaty, comes into force Wednesday.
