Alexander Busby
had selected his property east of the Munmurra to grow tobacco. He
was the son of John Busby who established Sydney’s water supply, and
brother to James who established the first viticulture in Australia
in the Hunter valley and George who was the medical officer in the
Bathurst district.
Alexander did
not have a great deal of rural experience but he was living on the
site, his family was well known among the officials of the colony,
his letters to Government was constant and from the outset he held a
position of importance. He was appointed Magistrate on 11 October
1832. He was 21 years of age. 
His 960
acres on the east bank of the Munmurra became the focal point for
administration of justice in the district.
The tracks from
outlying properties on the Talbragar River and Turee Creek, from the
south around the headwaters of the Goulburn River and from the
stations to the east on the Krui River and beyond to Bow and Gammon
Plains, led into the Busby property on the Munmurra River.
The property on
the east bank of the Munmurra was called Cassilis by Alexander Busby
to commemorate the noble Scottish lineage of his mother Sarah who
was the daughter of Robert Kennedy,
son
of the youngest brother of David, 10th Earl of Cassillis
(the second “l” being dropped later).
The homestead
was build by convicts from local sandstone and is a far cry from
Culzean Castle of Scottish Cassilis but it had been erected to
reflect the grandeur of his mother’s home.
In 1832 a
Constable and Scourger were employed by Busby to protect the locals
from bushrangers.
By 1835 he had
completed a slabbed timber lockup, courthouse and watch. The mail
service was established on 1 February 1836 on Busby’s property.
During the
1830’s various sites for a surveyed area for a registered village
were proposed. At the time Busby employed more than 68 people but
there were no stores and liquor shops.
However there
were buildings erected on the west side of the Munmurra on Dalkeith
property in the mid 1830’s to early 1840’s where the present village
of Cassilis stands and in 1839 John McKinley opened a store in the
vicinity of the current Post office and was appointed Post master in
November 1839.
In 1843 the
village area had been surveyed and lots sold.
In 1882 a
sandstone post office was built on McKinley’s site and more shops
and trade stores followed in the next fifty years, including several
hotels.
The village
remains unchanged to this day.
