Estimates of heat flow in Australia have been compiled in standard format rating the principal facts of each determination. Quality is assessed using a code that contains a summary of the sources of error. Estimates of precision vary according to the techniques used both in recording and processing of relevant geothermal data, but less obvious systematic errors are generated by changes in equipment design, core sampling rates, and local site conditions. Each factor must be considered when heat-flow values from different sources are being compared. The rating system has been tested for consistency, and a calibration provided that will allow the subjective quality factors to be used for numerical estimates of error. Heat-flow estimates were considered in two groups according to quality. Errors of 10 per cent (one standard deviation) were calculated for the group with better quality, but other estimates may contain errors of 20 per cent. New determinations of heat flow are presented according to the adopted format, and other data related to geothermal studies have been included to complement the existing data bank.
