As an Australian, inculcated with the orthodoxy that this was the largest island while also being the smallest continent - how does 'Oceania' fit with your quite technical 'big contiguous mass of land'?
If we made another small rut parallel to either Suez or Panama, would we add 1 to the count of continents?
Well, as per parent's logic, that claim is out the door ever since the Suez was dug out.
