[3] After being towed from Melbourne by a Japanese tug for 50 days, the 1943 Australian built drydock, formerly named AD 1001, was acquired by the Kuala Belait Shipyard.

[4][5][6] Kuala Belait is one of the largest human settlements in the district in which the river passes through,[3] while on the west bank lies the Kampong Sungai Teraban and Kampong Rasau.

[8] Some of Brunei's historical sites are located along the river banks, which included the Menara Cendera Kenangan, a monument in celebration of His Majesty's 50th birthday.
