[4] Before World War II, a ferry jetty was constructed at the end of Jalan Kuala Tutong, approximately 5 kilometres (3.1 mi) from Kampong Penabai.

Like other kuala settlements, its strategic position was likely chosen for defensive purposes and to facilitate trade and transportation along the river and nearby coastal areas.

The primary occupations of the villagers were fishing and farming, with their catches sold to Chinese traders who dominated commerce in the region.

[13] During World War II, the region became a battleground when the Australian Army's 20th Brigade and 2/8th Field Regiment fought against Japanese forces during the liberation of Brunei in August 1945.

In 1929, the transportation service was significantly improved with the introduction of the bantun, a large vessel formed by joining two boats, capable of carrying up to four vehicles and powered by a modified car engine.

This service, featuring boats named Higgins, Pemancha, and Semaun, charged a B$5.00 fare per vehicle and was predominantly used by employees of the British Malayan Petroleum Company.

Established in 1977 by Haji Mahmud bin Awang Damit, the company not only produces and repairs boats but also creates various fiberglass products.

At the time of its founding, fiberglass boats in Brunei were imported from Sabah and Sarawak, which motivated Haji Mahmud to start his own business.

During the Japanese occupation of Brunei (1941–1945), the jetty played a crucial role in allowing Australian troops access to the Seria oil fields, but it was damaged during the war and became unsafe.

After crossing to Danau, vehicles heading to Seria and Kuala Belait had to take a 25 miles (40 km) coastal route that was only accessible during favorable weather and tide conditions.

That year, a total of 17,855 buses and trucks, 7,840 Land Rovers and jeeps, and 751 motorcycles were recorded using the Kuala Sungai Tutong Ferry.

[21] Both government officials and Brunei Shell workers benefited from the improved ferry services, which facilitated easier vehicle crossings over the Tutong River.

On 21 May 1993, a new mosque was built on a 0.60 acres (0.24 ha) plot of land, located about 5 kilometres (3.1 mi) from Tutong town, and its construction was completed on 4 November 1993.

After the road connection between Kampong Penabai and Pekan Tutong was established, most villagers began performing Friday prayers at Hassanal Bolkiah Mosque.

Haji Nayan, believed to be a pious and revered Muslim convert from the Dusun ethnic group, originally resided in Kampong Tanjong Maya.

In the 1970s, a Chinese villager named Muncun reportedly survived a shipwreck by vowing to build a shelter at Haji Nayan's grave if he was saved, which he later fulfilled.
