TypeSuburbDetailsBerrilee is located on Bay Road, North Colah and it lays beyond Arcadia, on the road to Berowra Waters. Aboriginals used to trade fish with the local settlers and they called the pigs birra birra, and from this the name of the settlement, Birrilee, grew. The Bay Road corridor follows Berrilee Ridge down from Arcadia Park passing through the settlement of Berrilee above Berowra Waters. By 1905, Birralee had a Progress Association, though it had been the smallest and most remote of all the settlements in the Parish of North Colah. There have been numerous variations in spelling including Birrilee and later Berrilee. In the early 1900s Berrilee was known only as Calabash, which means "a gourd, or the dried, hollow shell of the calabash (tree), used as a vessel".
