ABC.net.au reports the Australian Border Force has seized 30 Indonesian fishers and destroyed three boats in a crackdown against illegal fishing in the 74,469 km2 (28,753 sq mi) Kimberley Marine Park, established in 2018, off Northwestern Australia. The combined catch of the three fishing vessels was over a ton of trepang (sea cucumber).

In addition to the loss of marine catch, there is fear that the fishermen, who frequently come ashore, may bring with them livestock diseases common in Indonesia but not present in Australia.
Australia has been seeing a resurgence of illegal fishing in their EEZ including Marine Parks, and there have been calls for more vigorous enforcement.


To me this is where making massive investment in unmanned ISR is absolutely needed so we can best marshal manned resources to effectively enforce.
