Australian Chart Index

The Australian Chart Index (ACI) is a text-based alternative to the AHO Chart Explorer.

Notice of Withdrawal

The Australian Chart Index (ACI) will be removed from the AHO website in the next few months. The ACI has been superseded by the AHO Chart Explorer, which provides an improved and more intuitive way to discover Australian paper nautical charts, Electronic Navigational Charts (ENCs), and related charting information.

Mariners using paper nautical charts are reminded of their responsibility to maintain charts in a fully corrected and up-to-date condition. The AHO will continue to publish Notices to Mariners, including chart correction information. Mariners should regularly review and apply relevant Notices to Mariners to ensure the ongoing accuracy of their paper charts and support the safety of navigation.

Mariners, chart agents and other users are encouraged to transition to the AHO Chart Explorer to identify chart coverage, access chart information and support voyage planning activities. The AHO Chart Explorer is now the primary chart discovery platform for AHO charting products.
