It strikes me as odd that this song contains both "verandah" and "porch" – two words that I thought were synonyms. Furthermore, I thought that, depending on what part of the world you came from, you might call it either a "verandah" OR a "porch" but it would be unlikely that both words would be in your everyday vocabulary—sort of like "pavement" vs. "sidewalk."

Am I wrong? Do these words mean something different in Australia?

(In Minnesota, people always call it a "porch." If you called it a "verandah" people would think you're not from around here, or else being very pretentious.)
