The ships reached Sydney in April 1825, and MacIntyre, after inspecting the best lands available, chose a locale for the uptake of the massive grant on the banks of the Pages River, east of modern-day Scone.
While MacIntyre was establishing Segenhoe, he also lost no time in furthering his own interests by requesting and receiving other grants of land in Hunter region for himself and his brothers.
Local Geawegal and Wonnarua Aboriginal people were pushed out of their lands by the arrival of the Scottish and made raids on the crops grown by these colonisers.
MacIntyre's brother, John, led a resultant punitive expedition but was forced to retreat when the Aborigines took up a high position and rolled rocks down upon them.
He prepared for his journey at Segenhoe, where MacIntyre became his friend and assisted Cunningham by guiding him through the difficult pass across the Liverpool Range on the initial stage of his expedition.
[2] By 1830, MacIntyre's own agricultural interests had become so profitable that he resigned from the managerial position at MacQueen's Segenhoe estate, where he was replaced by Hamilton Sempill.
[5] Large numbers of Aboriginal people resisted the occupancy of their lands at Byron Plains by spearing the shepherds and taking the livestock belonging to MacIntyre.
