Oceania is dominated economically by Australia and New Zealand, supplemented by the Pacific Island states (Papua New Guinea, Fiji, Solomon Islands, Vanuatu, Samoa, Tonga, Kiribati, Tuvalu, Nauru, Palau, Marshall Islands, Micronesia, Cook Islands, Niue, plus the French and US territories). Australia runs one of the world's most explicit points-test skilled-migration systems, with subject-specific occupation lists (the Skilled Occupation List, the Medium and Long-term Strategic Skills List, and the Short-term Skilled Occupation List) that determine which subjects get fastest-track migration access. The Australia view per subject documents the visa fit (Subclass 482 for employer-sponsored, 186 for permanent employer-sponsored, 189 for skilled-independent, 190 for state-nominated, 491 for regional, the Global Talent visa, plus the various student-to-work pathways through Subclass 500 / 485), the credential-recognition pathways (Engineers Australia, AHPRA for healthcare, CPA Australia and CA ANZ for accounting, etc.), and the major hubs (Sydney for finance and consulting, Melbourne for finance, education and tech, Brisbane for resources and Asia-Pacific HQ functions, Perth for resources and energy, Adelaide for defence and space, Canberra for government and policy).
New Zealand runs an even more streamlined skilled-migration system through the Skilled Migrant Category, the Accredited Employer Work Visa, and the Green List for shortage occupations. The New Zealand view per subject documents the points-test fit and the regional concentration (Auckland for finance, tech and primary-industry HQ; Wellington for government and creative industries; Christchurch for manufacturing and aerospace; Dunedin for academia; Hamilton and Tauranga for agriculture-and-horticulture).
The Pacific Islands are smaller economies but increasingly relevant for specific subjects — climate-and-environmental science (the Pacific is climate ground-zero), tourism management (a primary economic sector), public health and development (substantial donor-and-multilateral programmes), and remote-work/digital-nomad lifestyles (Fiji, Samoa and a few others run nascent DN-visa programmes).
