It includes a maritime dimension with Naval and Border Force ships patrolling the country’s territorial waters to prevent traffickers from smuggling asylum seekers into Australia.
A recent Amnesty International report condemned Australia for being "complicit in transnational crime" by paying smugglers $32,000 earlier this year to reroute a boat carrying some 60 migrants bound for New Zealand to Indonesia under Operation Sovereign Borders.
Ban met Turnbull on the sidelines of the 10th East Asia Summit in Kuala Lumpur, Malaysia, established on the initiative of the Association of Southeast Asian Nations (ASEAN).
