Overview
The Union Bank of Australia was a historical banking institution that operated in Australia and New Zealand from 1837 until 1951. It was established in London in October 1837 as a large joint-stock bank intended to serve the expanding economies of the Australasian colonies. The bank was created after Philip Oakden, a banker from Van Diemen's Land, travelled to England to seek support for a broader banking enterprise. Oakden obtained the backing of George Fife Angas, a prominent businessman and banker associated with the South Australian Company. The new institution began with subscribed capital of £500,000 and expanded through a combination of new branches and the absorption of existing colonial banking businesses. The bank's first operating branch opened in Launceston on 1 May 1838, using the premises of the struggling Tamar Bank, which the Union Bank had absorbed. Its expansion continued rapidly. On 18 October 1838 it entered Victoria by acquiring the Melbourne business of the Tasmanian Derwent Bank, described in the historical record as Melbourne's first bank. A Sydney branch followed on 2 January 1839. These early moves gave the Union Bank a presence in several major colonial commercial centres and helped establish it as a geographically distributed institution rather than a single-colony bank. The Union Bank also developed a trans-Tasman network. It opened its first New Zealand branch in Wellington in 1840. The bank initially agreed with the Bank of South Australia not to operate in South Australia, partly because of Angas's connections with that institution, but it eventually entered the South Australian market with an Adelaide branch in 1850. Later expansion included Brisbane in 1858 and Perth in 1878. By the late nineteenth century, its network covered the principal settlements and trading regions of the Australian colonies as well as parts of New Zealand. In 1880 the institution became a limited liability company, reflecting the development of more formal corporate structures in colonial banking. It remained solvent through the economic crises of the 1890s, a significant point in its history because those crises placed severe pressure on financial institutions in Australia. In 1892 the Union Bank acquired the Bank of South Australia, strengthening its position in that market and broadening its operations. The bank reached its centenary in 1937 with 267 branches and agencies across Australia and New Zealand. Its legacy is also visible in a number of former branch buildings that later received heritage recognition, including properties in Orange, Albany, Fremantle, Maryborough, Rockhampton and Townsville. The Union Bank ceased to exist as an independent brand in 1951, when it merged with the Bank of Australasia to create Australia and New Zealand Bank Limited. That successor is now known as ANZ, linking the Union Bank's historical branch network and institutional heritage to one of Australia's major contemporary banking groups.
History
The Union Bank of Australia was founded in London in October 1837 with subscribed capital of £500,000. Its creation followed Philip Oakden's effort to establish a substantial joint-stock bank capable of operating across the Australasian colonies. During a visit to England, Oakden secured the support of George Fife Angas, a businessman and banker who was associated with the South Australian Company. The institution then expanded its operations by absorbing the struggling Tamar Bank in Launceston, Van Diemen's Land. The first Union Bank branch opened in the former Tamar Bank premises on 1 May 1838. Expansion was swift. On 18 October 1838 the bank entered Victoria after acquiring the Melbourne business of the Tasmanian Derwent Bank. A Sydney branch opened on 2 January 1839, giving the institution an early presence in three important colonial centres. The bank crossed the Tasman Sea in 1840 when it opened a branch in Wellington, its first in New Zealand. Although it had initially agreed with the Bank of South Australia not to operate in South Australia, an Adelaide branch was eventually established in 1850. Further Australian branches opened in Brisbane in 1858 and Perth in 1878. The institution adopted limited liability in 1880. It survived the economic crises of the 1890s without becoming insolvent and used the period's restructuring environment to expand, acquiring the Bank of South Australia in 1892. Over subsequent decades, the Union Bank developed a substantial branch and agency network across both countries. At its centenary in 1937, it operated 267 branches and agencies in Australia and New Zealand. Several former Union Bank premises have since been recognised as heritage buildings. The surviving examples include branches in Orange in New South Wales; Albany and Fremantle in Western Australia; and Maryborough, Rockhampton and Townsville in Queensland. These buildings document the bank's geographic reach and the role of branch architecture in colonial commercial development. The Union Bank of Australia ended its independent existence in 1951 through a merger with the Bank of Australasia. The combined institution was named Australia and New Zealand Bank Limited and is now known as ANZ. The Union Bank is therefore both a defunct historical brand and a predecessor institution within the history of a major Australian banking group.
