Crossing the Blue Mountains

Crossing the Blue Mountains in 1813 opened vast grasslands inland from Sydney, transforming the prospects for sheep farming and wool exports in New South Wales. The crossing helped create the economic foundation of a powerful pastoral elite, while its association with William Wentworth—an expedition leader who later championed political inclusion—links territorial expansion to the colony’s struggle over who would share in its wealth and power.

The crossing and pastoral expansion

The Blue Mountains lay inland from Sydney, and their crossing in 1813 revealed extensive open grassland beyond them. For John Macarthur, who had begun raising sheep after arriving in Australia in 1790 and left the army in 1796 to concentrate on business, this was an opportunity: the newly accessible country offered abundant grazing land. Sheep farming and wool exports helped make Macarthur the colony’s richest man.

The land that supported this expansion belonged to the British government, not the pastoralists who grazed their flocks on it. Those landholders came to be known as the Squatters; as the colony’s elite, they were also described as the Squattocracy. The crossing therefore mattered not only as an opening of inland pasture but as part of the rise of an influential group whose wealth rested on access to public land.

Wentworth’s dual role

William Wentworth was one of the leaders of the first expedition across the mountains. The town named after him on the range preserved a connection to that journey. His part in opening grasslands to the Squatters stood alongside a markedly different political role: he became a prominent advocate for the rights of convicts, former convicts, and their children.

Wentworth called for an elected assembly, equal participation in elections, trial by jury for ex-convicts and their families, and an end to transportation to New South Wales. He founded the newspaper the Australian, which led attacks on the colony’s political institutions. The contrast is central to the crossing’s wider significance: one expedition leader helped open the landscape on which pastoral fortunes were built, then pressed for institutions that would give people beyond the established elite a voice in government.

Land, labor, and political conflict

The wealth generated by sheep farming did not make New South Wales an absolutist society. Unlike colonies in which elites could rely on serfdom or large Indigenous populations for labor, New South Wales depended on convicts as its workforce. Paying them wages was the means of encouraging their labor, and the resulting economic institutions were comparatively inclusive.

That arrangement was contested. In 1819, the British government sent John Bigge to investigate the colony. Shocked by convicts’ rights and the inclusive character of the economy, Bigge recommended that convicts be barred from owning land or receiving wages, that pardons be restricted, that former convicts be denied land, and that punishments become harsher. His proposals envisioned an autocratic society dominated by the Squatters. The political mobilization led by Wentworth and other former convicts and their children instead sought elected representation and participation in decision-making.

Significance

The crossing was a concrete turning point in the colony’s economic geography: it made extensive pasture accessible and strengthened a wool-producing elite. Its consequences were political as well as commercial. The fortunes of the Squattocracy depended on land controlled by the British government, while disputes over convicts’ wages, rights, and representation exposed competing visions of the colony’s future.

Wentworth’s place in both histories makes the episode especially revealing. He helped lead the journey that opened land to pastoral expansion, yet became a leading voice for broadening political institutions beyond the established elite. The crossing thus stands at the intersection of opportunity and conflict: access to land generated new wealth, while the distribution of rights and political power remained unsettled.
