Land orders, free immigration, and the discovery of gold were all factors in the development of the country, and the demand for farm lands led to the unlocking of areas previously given over to grazing. The pastoralists regarded agriculturists with disfavour, and in some cases with open antagonism. By the exercise of "pre-emptive rights," which their influence in the Legislature secured for them, they converted into freehold large blocks of the best land, as well as strategic areas by the possession of which they were able to close against settlement immense tracts preeminently suitable for farming. This was particularly the case in the settled districts of Moreton, Darling Downs, Wide Bay, and Burnett, and to a lesser degree in Maranoa. To such an extent was the right of preemption used that many squatters seriously crippled themselves, the price paid being too high for grazing to be remunerative on their freehold lands.

In the course of time railways were built through some of these large estates, but their earning power was seriously hampered by country capable of supporting a very large agricultural population being devoted to pasturing sheep and cattle. As the most satisfactory solution of the difficulty, successive Governments have repurchased a number of properties at a cost exceeding a million sterling, and resold them in small areas to farmers, with highly gratifying results both to the settlers and to the State.
