Abstract
The Australian Fundamental Gravity Network defines the datum, Isogal84, for gravity surveys conducted in Australia and the surrounding oceans. It consists of over 900 gravity stations at over 250 locations. Geoscience Australia has conducted measurements with a portable absolute gravity meter at a number of these stations in order to improve the accuracy of this network and to provide a consistent framework for gravity surveyors. These absolute gravity measurements show that Isogal84 is 75 microgals (1 microgal = 1x10-8 m/s2) higher than the absolute datum and that the accuracy of the stations within the network is approximately 30 microgals.
