The data in DealerNomics was prepared by global professional services firm BDO, who as a result of their significant specialisation in the motor industry, AADA and many franchised new car Dealers across Australia have established working relationships.

The model relies on a combination of publicly available information such as enrolled numbers by electorate, national new vehicle unit sales, tax and duty rates, as well as industry data such as BDO’s industry benchmarks, and our own data for the number of dealerships in each electorate.

The model also relies on a general assumption that there is a linear relationship between the number of dealerships in each electorate and the number of new vehicles sold in that electorate, and therefore the economic contribution to that electorate.
