Labor Left

 ( Australian Labor Party Factions ) 

The split played out differently across the country, with anti-communists leaving the party in Victoria and Queensland but remaining within in most other states. This created a power vacuum which allowed the Left to take control of the Federal Executive and Victorian state branch, while its opponents were preserved elsewhere. Tom Uren described the left of the Labor Party Caucus upon his election to Parliament in the late 1950s as "a loosely knit grouping... consisting mostly of anti-Catholics, although some members were militants or socialists".

From 1965, organised internal groups emerged to challenge the control of the Left, supported by figures such as John Button and Gough Whitlam. After the Victorian branch lost the 1970 state election in the midst of a public dispute with Whitlam over state aid for private schools, the South Australian Left, led by Clyde Cameron, and New South Wales Left, led by Arthur Gietzelt, agreed to support an intervention which saw the Victorian state branch abolished and subsequently reconstructed without Left control. Leftists in the Victorian party subsequently regrouped as the formally organized Socialist Left faction. In Queensland, the left coalesced around senator George Georges. Despite an increasing level of organisation in the grassroots party, this was not reflected within the Parliamentary caucus: Ken Fry noted that when he was elected to Parliament in 1974, meetings of left MPs were irregular and they responded to events in an ad hoc manner. The Labor Left suffered the loss of two of its key leaders in the mid-1970s with the downfall of Jim Cairns and the elevation of Lionel Murphy to the High Court of Australia, yet it continued to make advances in terms of nationwide organisation: right-wing power broker Graham Richardson has acknowledged that "at the beginning of the 1980s the Left was the only national faction".

In Tasmania, the Broad Left formalised itself in 1983, having taken control of the state party after reforms democratised it in 1976. In the Australian Capital Territory, the Left Caucus was founded after a left candidate was not Preselection in 1982. However, the Left was unable to translate their organisational advances into a presence in the Hawke government: although about a third of the Parliamentary caucus were aligned with the Left at the time, only one member was appointed to Hawke's first cabinet, Stewart West: leading left-winger Brian Howe placed high in the ministry ballot, but was relegated to a junior ministerial position. This came against the background of an increasing factionalising across the party and the emergence of a centre-left faction which joined with the Labor Right to dominate the Hawke government. Left influence was also restricted by the ALP's binding pledge committing legislators to accept caucus discipline, allowing members little freedom to dissent. Left influence also declined at the national conference, with the faction losing its conference majority in the early 1980s.

During the 1980s, prolonged disputes over tactical issues and personality conflicts resulted in a split occurring within the New South Wales Labor Left, creating two sub-factional groupings; the 'Hard Left' and the 'Ferguson Left', the latter of which was the successor of the Baldwinites. A significant event which caused the split was the election of the Secretary Assistant of the New South Wales Labor Party, where the Hard Left faction supported Anthony Albanese while the Soft Left faction supported Jan Burnswoods. The Hard Left faction was more closely aligned with left-wing groups external to the Labor Party, maintaining "closer links with broader left-wing groups, such as the Communist Party of Australia, People for Nuclear Disarmament and the African National Congress" as well as trade union officials, political staffers, lobbyists and student politicians, while the Soft Left's main base of support was among rank-and-file party branch members. In terms of tactics, the Hard Left favoured a top-down approach of transactional negotiation with the Labor Right, whilst the Soft Left advocated a continuation of the Baldwinite bottom-up strategy of mobilising the grassroots membership to win party positions. This difference in approach led to struggles between the two factions over candidate selections, with the Hard Left using their control over the party apparatus in tandem with sections of the Right to deselect Soft Left MPs across the state, particularly in western Sydney, Newcastle and Wollongong. For example, in Newcastle Bryce Gaudry was deselected in favour of the Right's Jodi McKay, following which about 130 members resigned or were expelled from the city's ALP branches, previously the largest in the state. The factions also had differing views on policy. While members of both the Soft and Hard Left opposed the Hawke/Keating government's privatisation of the Commonwealth Bank and Qantas, the Hard Left was seen as being more staunchly resistant to these changes.
