Yes, they do.

But note the following commentary in a Woolworth's submission to the ACCC last 
year, which highlights some of those data issues that can exist.

Further, AC Neilsen acknowledges these limitations.

The suggestion that Woolworths and Coles collectively have an 80% share of the 
market is limited for the following fundamental reasons:

*􀁸 AC Neilsen scan data is generally based only on dry packaged groceries. 
This category is but a narrow component of the grocery industry to which the 
Grocery Price Inquiry’s Terms of Reference relate. Furthermore, given the 
range of product categories that the Issues Paper states are of interest to 
the Inquiry and the different retailers participating in the sale of different 
categories of products, it is not reliable to assume that the category of dry 
packaged groceries can be used as a “proxy” for the entire grocery industry;11

*􀁸 AC Neilsen notes that scan data is collected for only a limited range of 
products, and in some cases is based on estimates (ie HomeScan data); 

* Given that AC Neilsen’s ScanTrak data for Woolworths, Coles, Franklins and 
some of the independents is based on point of sale (POS) data, and AC Nielsen 
itself states that POS data is not suitable for measuring retail share of 
trade, it is difficult to see how these data can be cited as being definitive 
of any sort of “market share”; and 􀁸 

* AC Neilsen’s data is obtained only from some outlets, resulting in a 
tendency to over-report the “share” held by those that are more represented in 
the survey.
