Why was Australia such a popular spot for Maltese?

Malta was under British rule and, although granted independance in 1947, argued about it until 1964. During that time, Maltese people were effectively British citizens and had the same rights regarding migration to Australia as other Brits. Malta was heavily bombed during WWII and at the end of the war had many displaced and homeless people. Consequently, a great many decided to migrate here as they qualified as "ten pound Poms". Migration from other European countries such as Italy and Greece was easy enough in the 1950s but it was easier still from Malta.
