AusENC are official vector Electronic Navigational Charts (ENC) providing coverage of Australian, Australian Antarctic Territory and Papua New Guinea waters published as 'AU' cells and coverage of Solomon Islands waters published as 'SB' cells.
They are authorised for use in IMO compliant Electronic Chart Display and Information Systems (ECDIS) and can also be used in compatible Electronic Chart Systems (ECS).
ENC deliver additional functionality over paper or raster charts when used in an ECDIS or suitable ECS. This additional functionality includes:
- Enabling vessels to navigate using real-time GPS positions displayed directly on the ENC,
- Enabling the ECDIS to respond to a safety depth contour based on vessel's actual draft,
- Look-ahead functions which enable dangers or hazards to be identified automatically and warnings and alarms raised,
- Provision of alerts and prompts for planned course alterations. The ability to customise the display and level of detail to suit the vessel, conditions and time of day.
Approximately 900 ENCs are included in the AusENC service.
For more information about ENC, ECDIS and ECS, see Electronic Charting Information.
AusENC are official vector electronic charts published by the AHO, Australia's national charting authority. AusENC allow:
- Vessels navigating in Australia on an IMO compliant ECDIS, to meet SOLAS Chapter V regulations covering the carriage of electronic charts and ECDIS. For further details visit the Australian Maritime Safety Authority (AMSA) website (www.amsa.gov.au).
- Commercial vessels 12 metres or more in length and engaged in Australian domestic operations, to meet the National Standards for Commercial Vessels (NSCV) when used in IMO compliant ECDIS or NSCV compliant ECS. For further details visit the Australian Maritime Safety Authority (AMSA) website (www.amsa.gov.au).
- Recreational vessels to sail both inshore and offshore.
ENC will be mandatory for most international commercial vessels under a rolling adoption programme running from 2012 to July 2018.
Note: AusENC are protected using Edition 1.1 of the IHO S-63 data protection scheme. See system requirements under FAQ for more details.

NtM updates are the means by which all national services provide the latest navigationally-critical information to mariners. It is therefore imperative for all mariners to update their charts and publications.

AusENC updates can be downloaded from the Product Downloads page.
Please see our Pricing page for all AusENC Pricing.
Where to Buy
AusENC packs are commercially available through AusENC Distribution Agents.
However, Australian port authorities may request AusENC that cover their area of port limits or areas of operation, directly from the AHO as part of data sharing arrangements. For further information, please contact the AHO Licensing Manager:
P: (02) 4223 6500
F: (02) 4223 6599

Does “S-57” data comply with SOLAS requirements?
No. “S-57” is an IHO transfer format and is not an official ENC. Anyone can produce “S57” formatted data but only official ENC complies with SOLAS requirements and carries the warranty of a National Hydrographic Office.
How are AusENC named?
All ENC adhere to an eight character naming convention controlled by the IHO. These identify the Producing Nation (first two characters), Navigation Purpose Code (third character) and Unique File Name (five characters). A more detailed explanation for naming of AusENC can be found in the fact sheet, ‘A guide to Interpreting AusENC Location-Based file names’.
In January 2016, the AHO commenced supply of AusENC Chart Service Certificates to customers with current AusENC pack subscriptions.
AusENC Chart Service Certificates confirm that, provided customers maintain their ENC for Updates, all ENCs in their AusENC packs listed on their certificate(s) satisfy carriage requirements of SOLAS Chapter V and Australian National Standards for Commercial Vessels up to the 'Licensed to' date shown on the certificate(s). These certificates can be presented to Port State Controllers for local inspection.
Certificates are automatically generated and emailed to customers when new subscriptions for AusENC packs are purchased and when subscriptions are renewed.
Separate certificates are supplied for each system installation / S-63 user permit that has current AusENC subscriptions.
To use AusENC you will need a navigation system which is “IHO S-63 compatible” and compatible with Edition 1.1 data.
The International Hydrographic Organization (IHO) introduced Edition 1.1 of the IHO S-63 data protection scheme on 1 January 2014. Since then ENC service providers like the AHO are required to deliver data in Edition 1.1 of the IHO S-63 data protection standard.
There are numerous navigation systems that are 'IHO S-63 compatible'. However, a small number of these systems may require an upgrade before they can use Edition 1.1. data.
To see if your system is compatible with Edition 1.1 data, consult your system manual or ask your system distributor. All ECDIS type approved from January 2009 are already compatible with S-63 Edition 1.1 data. To check the year of type approval for your ECDIS, look for the ECDIS wheel mark.
If you don’t have a compatible system and would like to purchase one, a complete list of all manufacturers who make IHO S-63 compatible systems can be viewed at S-63 Compliant OEMs. Alternatively you can contact your nearest AusENC distributor since some also sell S-63 compatible systems.
To place an order for AusENC you will need to:
1. Check whether your system is compatible with IHO S-63 Edition 1.1 data.
2. Supply your unique 'IHO S-63 User permit' to your AusENC distributor. If you have a system which is IHO S-63 compatible your system distributor will be able to provide this to you.
A free unprotected ENC data cell, covering an area of the Torres Strait including Varzin Passage is available for download and evaluation. Relevant technical information can be found in the readme file which can also be downloaded from here.
NOTE: Commercially available AusENC are protected using the IHO S-63 data protection scheme. Mariners wishing to use AusENC should check that their preferred viewing system is IHO S-63 compliant before purchase.
