[4][5] Siu A Chau is a recognized village under the New Territories Small House Policy.

[6] In 1937, Walter Schofield, then a Cadet Officer in the Hong Kong Civil Service, wrote that Siu A Chau was "another settlement of early man" and that it had a "fishing village of huts very different from ordinary Chinese dwellings" at the time of writing.

[4] A low-level radioactive waste (LLRW) facility began operation at Siu A Chau in July 2005.

Low-level radioactive wastes which had previously been stored in disused tunnels, two factories and five hospitals were subsequently transferred to the Siu A Chau facility.
