[4] Another version tells of a Dusun villager suffering from a highly contagious disease called Supak.

Believed to be incurable, the individual was relocated to an isolated hill and left to die, leaning against a large tree.

Initially, iau referred specifically to the tree associated with these events, but over time, the term became the name of the location and later the village.

[7][8] The first ketua kampung (village head) of Kampong Bakiau, appointed by the residents, was Dollah bin Imam Sulong.

In 1982, Pengiran Haji Othman was appointed as penghulu of Mukim Kiudang, a role he held until 1999, during which he was also responsible for acting as the village head of Kampong Bakiau.

Upon completion, the school enrolled 29 students—14 boys and 15 girls—studying in Primary I and II under the leadership of its first headmaster, Umar Ali bin Esong.

The hill was named after a bird called the tiung (Myna), known for its remarkable ability to mimic human speech.

According to oral tradition in Kampong Bekiau, a villager once kept a tiung and taught it to speak whenever he approached or fed it.

The enemy grew anxious and confused, thinking that their movements and hiding places were being observed by the villagers.

Fearing an imminent attack, they became too frightened to stay and decided to flee, abandoning their plans to launch an assault.
