ISA has been collecting data on comprehensively insured private and business passenger vehicles since 1988. Over this period a comprehensive database has been established from which a number of syndicated reports are produced each quarter.

The Motor Claim Type Report provides detailed information on the principle causes of loss (or claim type) for motor vehicles at both a state and Australia wide basis.

The Motor Trend Report is an interactive report which enables ISA members to view information for any selected combination of claim type and state for each quarter since March 1993.

Trend Summary Graphs provide a visual representation of changes to market share, premiums, claim frequency, claim size and loss ratios over time.

The table below provides an indication of the data collected and reported on to members of the ISA Motor Syndicate as at December 2016. The figures represent 12 monthly rolling averages for Australia as a whole.
