Bulkers trading between the Far East and Australia could be forced divert to the Philippines to change crew or face port-state control detention.

The Australian Maritime Safety Authority (AMSA) said it will enforce strict new rules on crew length of service starting today.

AMSA is no longer overlooking Maritime Labour Convention 2006 (MLC) violations involving seafarers working beyond their contracted period, in a bid to force shipowners to repatriate increasingly overworked, stressed and homesick crew.
