If you are talking about the ginger nut biscuit, then you will simply need to declare it when you come in through Australian customs. Customs will decide whether you can bring them into the country, or whether they will be confiscated. If you do not declare them, and they are discovered in your luggage or on your person, then you may be subject to prosecution or fines. We do have gingernut biscuits in Australia - they might just be a little different in flavour or texture. If you are referring to ginger nuts - not biscuits - then again, you will simply need to declare them (and any other food you bring in) when you come into the country.
