This official collection of Electronic Navigation Charts is produced by the Australian Hydrographic Office. It conforms to S57 IHO Standards and requires an S63 compatible system to operate. ENC are primarily produced to support the safe navigation of commercial shipping, but are equally useful for recreational vessels. ENC can, when used on a Type approved system, replace the need for paper nautical charts.
This AusENC packs contains all the Category 3, 4, 5 and 6 cells which overlap the area depicted in the map. The mapped area is based on the outer coverage of the category 5 and 6 cells within this pack. The category 3 and 4 cells not shown so as to avoid clutter. This pack does not include any category 1 or 2 cells.
For extensive detail on the symbology of nautical charts, the Admiralty Guide to ENC Symbols used in ECDIS is the definitive reference.
All AusENC packs are supplied as a subscription. This subscription gives you access to the updated information supplied by the Hydrographic Office throughout your subscription period.
Once your subscription is established, the Hydrographic Office will email you your permits (a small text file to load into your system), and then each fortnight will email you to advise if new permits need to be installed. This fortnightly email will also contain a link to the latest updates available.
Nearing the end of your subscription, we will contact you directly to confirm your requirements for a further renewal. You may also receive similar alerts from the Hydrographic Office.
