[6][7] In 1827 Captain Patrick Logan, commandant of the Moreton Bay penal colony, made an expedition to Mount Barney.

In 1842 William Humphreys, a sheep grazier on the Liverpool Plains, took up several thousand acres on the Albert River and established a pastoral property, or station (Depasturing License number 661).

The eldest sons, Robert and William, helped introduce cattle (sheep were moved to properties further west when they proved unsuitable for coastal country[14]).

[16][17] Mundoolun's association with investigating the tick-borne disease of cattle caused by blood parasites, known as tick fever or red water (babesiosis, anaplasmosis), began with William Collins, the second son of John and Anne.

[18][19] The following year in 1897, cattle on the Collins's Mundoolun station were inoculated in pioneering experiments for tick fever conducted by Charles Joseph Pound of the Queensland Stock Institute.

Inoculum was sourced, directly and by passage through calves, from steers of Inkerman Station in northern Queensland which had recovered from tick fever.

Pound's observations were reported to include: cattle were a host for the disease "germ", and indications that immunity may be acquired in utero or induced by inoculation.

Situated west of Mundoolun Road, the church was built from local sandstone to a design by John H. Buckeridge, Diocesan Architect of Brisbane at the time.

[24] In the cemetery is the grave of Bullumm (1850–1931), also known as John Allen, the last survivor of the Wangerriburra people and a lifelong associate of the Collins family.

[25] In 1913 Bullumm helped John Lane, headmaster of the Jimboomba State School, to compile the Wangerriburra language, and their work was included as an appendix in the 1913 annual report of The Chief Protector of Aboriginals.

The report notes the suitability of the site due to the quality of water from the Albert River at Mundoolun for drinking, washing, and swimming.

[27] One member of the Collins family, Douglas Martin Fraser (1888–1968), served with the 5th Light Horse Regiment in Palestine during 1918.

[citation needed] Formerly in the Shire of Beaudesert, Mundoolun became part of Logan City following the local government amalgamations in March 2008.
