OFFICIAL NAUTICAL PRODUCT
AusTides is an official nautical publication. Official nautical publications are those issued by, or on the authority of, a Government authorised Hydrographic Office or other relevant government institution. The Australian Hydrographic Office (AHO) is Australia’s national charting authority and publishes official nautical publications of the Australian Charting Area.
For details about carriage requirements of nautical products in Australian waters for SOLAS and NSCV regulated vessels, visit the Australian Maritime Safety Authority (AMSA) website (www.amsa.gov.au) and refer to Marine Orders and Marine Notices.
Admiralty Tide Tables and Admiralty TotalTides are also official nautical publications. Minor differences in the times of predictions may occur when using Admiralty products.
PURCHASE / DOWNLOAD
AusTides is released annually, towards the end of the year and provides tidal predictions for the following calendar year.
AusTides is published as a download available from our Product Downloads page.

- A Standard Port (also referred to as a 'Primary Port') is a place for which independent daily tidal predictions are given in the tidal height or tidal stream tables. Predictions are typically based on observations over several decades.
- A Secondary Port is a place for which tidal predictions given the tidal height or tidal stream tables are calculated by applying relevant corrections to the tidal predictions of a standard port. Predications maybe based upon lesser periods of continuous observations.
- Predictions in ANTT for times and heights for high and low water are referenced to Lowest Astronomical Tide (LAT), which is chart datum for most large scale Electronic Navigational Charts (ENC) and paper nautical charts covering ports. However, chart datum for some ports differs from LAT.
- While short term predictions for Australian Standard Ports are also available from the Australian Bureau of Meteorology (BoM), it should be noted that the latter do not take into account differences between chart and tidal datums. Predictions for Secondary Ports are not available through the BoM website.
- For more information on vertical datums refer to section 12.9 in The Mariner's Handbook for Australian Waters.
