Please don't take the numbers in the food table as gospel, there will be some mistakes.
For example I found that a few of the egg entries have arachidonic acid values of zero, which is incorrect. (If an entry is blank it means there is no data for that nutrient, but zero values should only be present if tests have been done and the nutrient wasn't present (or was below the lower limit).)
This is quoted from FSANZ:
Limitations of food composition data
There are limitations associated with food composition databases. Nutrient data published in NUTTAB 2010 may represent an average of the nutrient content of a particular sample of foods and ingredients, determined at a particular time. The nutrient composition of foods and ingredients can vary substantially between batches and brands because of a number of factors, including changes in season, changes in formulation, processing practices and ingredient source.
While most of the data contained in NUTTAB 2010 are generated from analysed values, some of the data are borrowed from overseas food composition tables; supplied by the food industry; taken from food labels; imputed from similar foods; or calculated using a recipe approach.
While FSANZ has made considerable effort to ensure the quality of data in NUTTAB 2010, FSANZ makes no warranty that the information contained in NUTTAB 2010 will be free from error, or if used will ensure compliance with the relevant requirements of the Australia New Zealand Food Standards Code.
Also, in their explanatory notes they state:
In some of the older analyses used in NUTTAB, there may be misidentification of some long chain polyunsaturates.
So again, please just regard the values in the food table as a guide and investigate further if you suspect an error and the value is important to you.
