Bullabulling is a small Goldfields townsite located 526km East of Perth. Initially gazetted in 1898 as Bull Bulling, before being amended to Bullabulling in 1944. The central attraction of the town was the Rock Hotel roadhouse, built in 1896 and operated by the Palmer family.

An 1893 survey plan shows a man-made soak on Bullabulling Rock, later used to supply water by building dams to catch the water. Reserve 2919, covering the Bullabulling Rock catchment, channels and dam was gazetted in 1895. A key water source for travellers and steam locomotives, the Bullabulling Rock water reservoir played a key role in the development of the Eastern Goldfields.

In 1902, the Eastern Goldfields line was connected to the Goldfields water supply, including Bullabulling dams as a main railway water supply. With the introduction of diesel engines to the Eastern Goldfields line, by 1956 the Bullabulling Rock water dam was no longer required.

The Rock Hotel and Bullabulling dams are all that remains of the town. The Rock Hotel was closed in 2015, catering to passing travellers by the Minozzi family since 1955.

The project GEO1 will be based in the Bullabulling area, using GNSS to observe survey marks along the Great Eastern Highway level traverse, extending approximately 100km. The observed height differences will be compared on the AUSGEOID2020, AUSGEOID09 and AGQG2017 (quasigeoid). These will then be compared to the spirit levelled height differences of the level traverse, with the intentions of challenging the traditional method of spirit levelling, using one-way GNSS height differences. The upgrade of benchmark (BM) SCK47 to Standard Survey Mark (SSM) will also be carried out.
