Corridor intel — Australia ↔ Southeast Asia
Perth and Darwin are Australia's cheap back doors to Asia. Jetstar, AirAsia X, VietJet and Batik Air run monthly sales — Friday afternoons (AEST) for Jetstar's Friday Frenzy. Bali and Kuala Lumpur are the two cheapest entry points; everything in SEA is a $30–80 hop from KUL.
