Accuracy - how close do the pixels match their real location? Measurements or coordinates taken from the imagery can imply a contractor has constructed something in the incorrect location or a building encroaches an adjacent property - comparisons with other data such as engineering design or legal boundaries. Don't know if NEA state the accuracy but we find metres of discrepancy - this is acceptable depending on what the user is doing with the data - fine for broad environmental studies, marketing catchments, asset management.
Image consistency - some areas can be blurred and others sharp, the colours are not particularly well balanced so stable colours change significantly with different surveys and even a similar feature within different areas of the same survey. Their mosaic lines have significant steps in them which is not pretty but can also lead to errors in what the user does with the data as per accuracy (eg derived areas are incorrect, alignments are altered along and across contradicting the truth). It's just a matter of determining it's fitness for purpose
