Mrrzy,

Zucchini is a small summer squash or marrow, but I have never heard it called anything other than zucchini or courgette. It became well known in Oz probably through the Italian influence on Oz cuisine. I had never heard of it until the mid-70's - coming from a true-blue Aussie home with meat-&-3-veg and pudding every night at dinner. (I remember in the late 60's when Mum had bought a pre-mix packet to make pizza - that was a failed experiment on behalf of the manufacturers. Not the nicest meal I ever ate.   I never had store-bought pizza until about 1973.)
