At its 11th Meeting (Brisbane, Australia, Feb. 2012), the SWPHC established an International Charting Coordination Working Group (ICCWG) to develop and maintain official nautical charts, in both paper and digital formats, that support ships engaged on international voyages in Region L.

Accordingly, ICCWG is in charge of coordinating INT chart and ENC schemes,  

The SWPHC ICCWG is a subsidiary body of IHO’s regional South West Pacific Hydrographic Commission (SWPHC).  Its work is subject to SWPHC approval.
