To argue that the Portuguese had never been to the continent is incorrect. Moreover, maps were either not made or lost a lot. Given Portuguese activities in the region in general, they'd have visited the northern coast at some point. Just wasn't worth doing anything.

The Brits already had a settlement in Western Australia, even in that very region, by the end of 1826.
