The Asia & Oceania tab includes locations to find resources on Asia (particularly South Asia and East Asia) and Oceania (particularly Australia and New Zealand). As coverage is uneven for these regions, I would recommend using general databases to find more specific sources.
Keywords:
For Asian migration due to indentured servitude, search "Coolie."
For migration to Australia and New Zealand, search "Ten Pound Poms Scheme" or "Assisted Migration."
