The SOE eventually settled on a small and isolated island known as Tanjong Balai. Located at the mouth of Sungei Jurong, the island was where a single man-made structure, consisting of a lone bungalow that was once owned by Jewish businessman Joseph Brook David, was located. Apart from the bungalow, the island was also well-hidden amongst the canopy of secondary-type rainforest and what was even better was the convenience of accessing the location either by a boat or by a well-hidden path in the jungle.
