How much money you will receive really depends on the extent of your injuries and your losses.
It is also affected by factors like your age, amount of lost earnings, care you need now and in the future, out-of-pocket expenses and possible future expenses such as surgery.
Once your injuries have stabilised that you will have a better idea of what you can claim.
If the airline accident caused the passing of a relative, the amount will depend on a number of things such as relevant international conventions (if any), if the claim is being pursued in Australia or overseas, and if there is a faulty product involved in the claim.
