The RAN Australian Hydrographic Service conducted hydrographic survey HI320 at Commonwealth Bay, December 2000 to January 2001. The survey area was the north and north-west coast of Cape Denison, including Boat Harbour. Some survey lines were also followed further out in Commonwealth Bay, including in the vicinity of Mackellar Islands.

The survey was conducted by LCDR J.Daetz. The data are not suitable for navigation.

Tide gauge data collected from two platypus gauges (TG040 and TG041 - barometric) at Commonwealth Bay. Data were collected between 2007-11-27 and 2010-02-16. The gauge was a bottom mounted pressure sensor with a self-contained logger. Sea temperature and barometric pressure were also recorded. Further information is also available from the National Tidal Centre at the Bureau of Meteorology.
