Biraban (c. 1800 – 14 April 1846) was a leader of the Awabakal people, an Aboriginal Australian people who lived in the area around what is today Lake Macquarie. His native name prior to Awabakal initiation was We-pohng; his naming as Biraban is reference to his totemic relationship with the eaglehawk.

We-pohng was born at Bahtahbah (Belmont, New South Wales) c.1800. During his childhood We-pohng was abducted by the British and raised within the military barracks located in Sydney. Subsequently, We-pohng was assigned to Captain John M. Gill, a member of the 46th Regiment. We-pohng remained with Captain Gill from February 1814 until Captain Gill departed Australia in December 1817. It was at this time We-pohng became fluent in English and was bestowed the name M'Gill (and its derivatives) by the captain as "a mark of his claim on the boy."

We-pohng, with two other young Awabakal men named Bob Barrett and We-rah-kah-tah, were assigned to Captain Francis Allman in 1821 to assist in the establishment of a penal colony at Port Macquarie, assuming the role of regional guide, interpreter and a 'bush constable'. We-pohng, We-rah-kah-tah and Bob Barrett were utilised for their tracking skills to apprehend escaping convicts.

Prior to his return to Newcastle in 1825 We-pohng married Ti-pah-mah-ah, with whom he had one son, Ye-row-wa.

From 1825 Biraban served as an informant to the missionary Lancelot Edward Threlkeld teaching him the Awabakal language and cosmology.

In 1826 Biraban experienced his Awabakal clan initiation in which he was transposed from boyhood to manhood. Subsequently, Biraban acted as a spokesperson for the Awabakal clan, with part of his duties involving reporting 'assaults on Aboriginal people to Threlkeld who, in turn, reported them to the colonial authorities,' and acting as a distributor of British material goods to Aboriginal people.

Biraban assisted Threlkeld to establish a Mission of the London Missionary Society (LMS), and later the Colonial government Ebenezer (mission), on Awabakal land. In preparation for the LMS Mission Biraban worked alongside two other indigenous men to fell 'trees to make room for the erection of…[a mission] house and prepare for planting some Indian corn.'

Speaking English fluently Biraban was frequently called upon by the colonial government to act as an interpreter between Aboriginal clan members and settlers. A notable work in which Biraban was involved was the interpretation and transcription of Christian religious texts into the Awabakal language. Threlkeld recognised the value of Biraban as his local teacher, writing, '[i]t was very evident that M'Gill [Biraban] was accustomed to teach his native language, for when he was asked the name of anything, he pronounced the word very distinctly, syllable by syllable, so that it was impossible to mistake it.' It was later admitted by Threlkeld that Biraban was crucial to his translation work, with the Awabakal translation and publication of the Gospel of Luke being 'principally translated by Macgill himself.'
