Phil B dropped me a note this morning with this really  useful graphic showing our maritime search and rescue zone.  Makes you wonder how it ever came to be taken for granted that we'd just look after open waters south of Java.

Here's Phil:

We hear almost daily about Indonesian's Search and Rescue Zone - but few would understand just where it is - This map is from the AMSA web site and shows Australia's Search and Rescue Zone in the dark shades - it extends south to Antarctica. It appears from media reports that all Operation Sovereign Borders vessels are now operating within the Australian Search and Rescue Zone.
