Is it field corn from a farm or "sweet corn" from a grocery store?
If it is sweet corn you need to let it dry down in the house until it loses its flexibility and feels good and dry to the touch - I would let it dry for at least a month. You could microwave it on a very low setting a few times to speed the process.
If field corn, when was it harvested? If it was harvested and shelled more than a couple weeks ago, it should be fine. I imagine it is quite dry in Perth - it should dry down very quickly.
