Solomon Islands pound
The pound was the currency of the British Solomon Islands Protectorate between 1899 and 1966. It was divided into 20 shillings, each of 12 pence. Initially, sterling coin circulated, supplemented by local banknotes from 1916. In 1920, Australian coins and banknotes were introduced, although local paper money continued to be produced until 1932. When the Australian pound broke its parity to the sterling in 1930 during the Great Depression, this caused uncertainty in the British territories of the Western Pacific regarding whether their pound unit was a sterling or an Australian pound. This uncertainty prevailed into the mid-1930s and was only resolved when the matter was clarified by King's regulations. The final result was that all the British territories apart from Fiji adopted the Australian unit. As such, the British Solomon Islands Protectorate followed the course of Australia.
Between 1942 and 1944, the Solomon Islands were occupied by Japan and the Oceanian pound circulated. The Australian pound returned after the war and was replaced by the Australian dollar in 1966. This was, in turn, replaced by the Solomon Islands dollar in 1977. For a more general view of history in the wider region, see British currency in Oceania.
