AusTides is an official electronic product that is equivalent to paper Australian National Tide Tables (ANTTs). AusTides contains information for over 680 Primary (Standard) and Secondary ports in Australia, Papua New Guinea, Solomon Islands, Antarctica and Timor-Leste. This information includes but is not limited to:
- Predictions for high and low water for each day of the year for over 680 ports with tidal curves and predictions at each port location presented graphically at 10, 20, 30 and 60 intervals.
- Predictions of maximum rates with graphical curve of tidal streams for Torres Strait and Port Phillip Heads.
- Tidal Stream diagrams for Sydney, Broome and Darwin.
- List of the main 22 harmonic constituents for all Standard and Secondary Ports.
- Tidal levels for all ports listed.
AusTides are official electronic tide tables published by the AHO, Australia's national charting authority. AusTides allow:
- Vessels navigating in Australia to meet SOLAS Chapter V regulations (and AMSA regulations1) covering the carriage of charts and publications. 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). For further details visit the National Marine Safety Committee (NMSC) website (www.nmsc.gov.au).
- Recreational vessels to sail both inshore and offshore.
Note 1: See AMSA Marine Orders Part 21, Order 6 of 2010, which details carriage requirements for nautical charts and publications necessary for the intended voyage.
AusTides are published on CD-ROM. They are released annually in October and provide tidal predictions for the year of release and the following calendar year.

What is a standard port?
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.
What is a secondary port?
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.
Where can I find more information about Tides?
