A renewed debate over Australia’s national identity has emerged just days before the Australian Labor Party’s National Conference in Adelaide, after one of the country’s most influential trade unions called for the Union Jack to be removed from the national flag.

The proposal comes from the Australian Manufacturing Workers’ Union (AMWU), which is urging Labor delegates to support replacing the current flag with a design that no longer includes Britain’s Union Jack. The union argues the existing flag continues to represent Australia’s colonial past and carries symbolism that many Aboriginal and Torres Strait Islander Australians associate with dispossession and oppression.

The motion is expected to be considered as part of a broader package of policy proposals ahead of Labor’s 50th National Conference in Adelaide, where thousands of party members, union delegates, parliamentarians and supporters will gather to debate the party platform for the coming years.

The AMWU says Australia should adopt national symbols that better reflect the country’s modern identity rather than its colonial origins. According to the union, while contemporary Australians are not personally responsible for historical injustices, they continue to benefit from institutions established during colonisation and therefore have a responsibility to address those legacies.

The proposal forms part of a much wider agenda that also includes stronger recognition of First Nations Australians, expanded social welfare measures, new taxes on wealth and inheritance, and increased taxation of gas exports to fund public services and reduce inequality.

Despite the union’s push, there is little indication that senior members of the Albanese government are prepared to embrace a change to the national flag.

Housing Minister Clare O’Neil was questioned repeatedly about the proposal during media appearances before eventually stating she did not personally support changing the Australian flag, signalling that the issue is unlikely to become official government policy regardless of debate inside the party.

Her comments highlighted the political sensitivity surrounding one of Australia’s most enduring national symbols.

Opposition figures were quick to criticise the proposal, arguing Australians expect political leaders to focus on cost-of-living pressures, housing affordability and economic management rather than symbolic constitutional or cultural issues.

Nationals Senate leader Bridget McKenzie defended the existing flag, arguing it reflects Australia’s British democratic heritage while also incorporating uniquely Australian elements such as the Commonwealth Star and Southern Cross. She said the institutions inherited from Britain helped establish Australia’s parliamentary democracy and legal system.

Independent MP Dai Le also rejected changing the flag, arguing it represents opportunity for migrants who have built new lives in Australia and saying practical issues facing families should take priority over debates about national symbols.

The controversy has revived a debate that has surfaced repeatedly over recent decades but has never produced political consensus.

The current Australian national flag was first selected in 1901 following Federation after a public design competition. It combines the Union Jack in the upper left corner with the Commonwealth Star beneath it and the Southern Cross constellation on a blue field.

Supporters of retaining the existing design argue it represents more than Australia’s historical relationship with Britain. They say it honours generations of Australians who have served under the flag during military conflicts, humanitarian missions and peacekeeping operations while also symbolising continuity and national unity.

Those advocating change argue Australia’s identity has evolved significantly since Federation.

They contend the country’s multicultural society, growing Indigenous recognition and increasingly independent foreign policy justify adopting a flag that better reflects modern Australia rather than its colonial beginnings.

The issue is closely linked to wider debates surrounding constitutional recognition, reconciliation and Australia’s relationship with the British Crown.

Although Australia became fully sovereign through a gradual constitutional evolution during the twentieth century, it remains a constitutional monarchy with King Charles III serving as Australia’s head of state.

Discussions about becoming a republic have periodically revived calls for a new national flag that would remove British symbolism altogether.

However, polling over many years has generally shown Australians remain divided over replacing the current design.

While support exists for a new flag among some sections of the community, surveys have frequently found a majority of Australians either prefer the existing flag or believe any change should only occur following broad national consensus or a referendum.

The latest proposal arrives at a politically sensitive time for the Albanese government.

Labor’s National Conference represents the party’s highest policy-making forum and often becomes the stage for internal debates between ministers, grassroots members and affiliated unions over issues ranging from climate policy to taxation, industrial relations, foreign affairs and constitutional reform.

Although unions continue to play an influential role within Labor’s organisational structure, conference resolutions do not automatically become government policy.

Instead, they often serve as indicators of pressure from sections of the broader Labor movement and can influence future policy discussions even when ministers decline to adopt them immediately.

Political observers note that this year’s conference is expected to focus primarily on economic management, artificial intelligence, industrial relations, housing affordability, energy policy and Australia’s strategic position in an increasingly uncertain global environment.

The flag proposal therefore risks becoming one of several symbolic issues competing for attention alongside more immediate economic concerns affecting Australian households.

For supporters, however, symbolism itself carries significant importance.

They argue national flags communicate a country’s values both domestically and internationally, making them powerful expressions of identity rather than merely ceremonial objects.

Many Indigenous advocates have long argued that removing colonial symbols would represent another step in Australia’s ongoing reconciliation journey, even if practical policy reforms remain the greater priority.

Critics counter that changing the flag would do little to improve living standards or address disadvantage and could instead deepen political divisions over history and national identity.

As Labor delegates prepare to meet in Adelaide, the proposal has once again demonstrated how debates over Australia’s past continue to shape conversations about its future.

Whether the motion ultimately receives significant support or fades into the background of conference proceedings, it has already reignited broader questions about what Australia’s national symbols should represent in the twenty-first century and how the nation balances respect for its historical foundations with an evolving multicultural identity.
