In the years following World War II, Melbourne experienced rapid growth, fueled largely by post-war immigration from Southern Europe and the Mediterranean. This influx of new residents helped shape the city’s multicultural character. While the “Paris End” of Collins Street became known for boutique shopping and open-air café culture, the broader city centre was often seen as stale, a sentiment famously captured by John Brack in his 1955 painting Collins St., 5 pm. During much of this period, Melbourne was considered Australia’s industrial heartland.

Significant changes to the city’s skyline began in 1958 with the construction of ICI House (later Orica House), which marked the end of strict height limits in the CBD and the beginning of Melbourne’s era of skyscrapers. Suburban expansion accelerated, supported by the development of indoor shopping centres, including Chadstone. The post-war era also brought a major renewal of the CBD and St Kilda Road, modernising much of the city. Many older pre-war buildings were demolished or retained only as facades, while large suburban mansions were either subdivided or replaced.

To counter low-density suburban sprawl, the Housing Commission of Victoria launched controversial public housing projects in the inner city, resulting in high-rise towers and the demolition of existing neighbourhoods. The rise of motor vehicle ownership spurred extensive freeway and highway development, including major projects like the remodelling of St Kilda Junction, the widening of Hoddle Street, and the ambitious 1969 Melbourne Transportation Plan, reshaping Melbourne into a car-oriented city.

Economic growth during the late 1960s and 1970s attracted the headquarters of major companies, including BHP and Rio Tinto, while Nauru’s then-booming economy led to investments such as Nauru House. Melbourne remained Australia’s primary business and financial centre until the late 1970s, when Sydney gradually overtook it.

The city experienced a severe economic downturn between 1989 and 1992, following the collapse of several local financial institutions. The Kennett government, elected in 1992, initiated an ambitious recovery program that combined public works development with a focus on tourism, major events, and sports. Key projects included the relocation of the Australian Grand Prix from Adelaide to Melbourne, and the construction of landmarks such as the Melbourne Museum, Federation Square, Melbourne Convention & Exhibition Centre, Crown Casino, and the CityLink tollway. Strategies also included privatisation of certain services and reduced funding for sectors like health, education, and public transport, reflecting a new era of economic and urban transformation for Melbourne.
