Dear Gunapathi,
Thks for the interesting link.
In the interests of Science I tried out the link. 
Some people will be daunted by the questionnaire to get to the full database. i was one of them and didn't proceed.
On the other hand getting to the recipe section is less demanding despite the forboding text box, ie clicking "agree" on next page not too difficult.
The next page just requires an arbitrary input, eg recipe1 > continue, click
Next page just type in anything of interest and the data comes up. I presume this accesses the total database.
The results are variable. Perhaps reflecting the Australian eating habits ?
eg
potato - 65 hits
shark - 4 hits
shrimp - 1 hit
kangaroo - 5 hits
Unfortunately no species info is given within the search output. Maybe it exists in the full database.
The help file is quite good, and also honest, eg -
However, the NPC has limitations when the preparation of your food involves boiling or frying, especially where the water or oil is not completely absorbed by the food.
The NPC also has limitations when the preparation of your food involves baking with yeast (fermentation), fermentation (with other bacteria e.g. yoghurt) and other certain processes.
If you make these types of foods, it is important for you to become acquainted with these limitations and ways to get around them. For further information, see Section 11 of the full Explanatory Notes.
(Was unable to see any directions to section 11.)
Bear in mind that the NPC database does not have an extensive range of raw/unprocessed ingredients, meat cuts devoid of separable fat and products that are used exclusively by the food industry (ingredients, food additives or processing aids e.g. enzymes), so it is possible that the ingredient you are looking for simply isn’t on the NPC database.
Nonetheless, certainly interesting to browse through. Whether viable to put on a labelling panel is more uncertain? Maybe not intended for such purposes ?
Personally i have always had to submit samples to a lab since i didn't have access to the more famous/standard texts on the subject.
