The core assertions of this claim are well-supported by empirical evidence from multiple independent sources.
**Consistently Optimistic Forecasts:** During the Coalition government period (2013-2022), Treasury's wage growth forecasts proved "wildly optimistic, with actual wages growth falling well short of expectations" [1].
The 2019 budget exemplified this pattern: "Despite a slowdown in wage growth in late 2018, the budget simply replicated the previous year's wage forecast delayed by one more year" [1].
This pattern continued through Mid-Year Economic and Fiscal Outlook (MYEFO) revisions, with wage forecasts repeatedly downward-revised year after year [2].
**Failure to Materialize:** By 2019, "Australian workers had not seen real average wages rise in over 5 years" despite consistent forecasts predicting wage growth was "just around the corner" [1].
The actual performance under Coalition governance showed nominal wage growth averaging just 2.2% annually, with workers experiencing essentially stagnant real wage growth over the entire nine-year period [3].
When Labor took office in 2022, real wage growth in a single year (2023-24) exceeded the entire nine-year Coalition record [3].
**Pattern Across Multiple Years:** Treasury's MYEFO in December 2019 downgraded the wage forecast from 2.75% (April budget) to 2.5%, confirming "another downward revision," indicating this was not an isolated forecast miss but a systematic pattern [2].

**Why the Optimistic Forecasts Were Made:** The claim attributes forecast optimism to lack of economic rationality, but research reveals an important structural reason.
Analysis indicates that "rosy wage forecasts were helpful in justifying equally optimistic revenue forecasts, since if Australians earned more money, they would pay more taxes" [1].
This suggests the forecasts served a fiscal justification purpose within budget documents rather than reflecting genuine Treasury economic modeling.
**Labor Government Forecasting Record:** The claim does not address Labor's wage growth forecasting history.
The searches conducted did not locate systematic comparisons of Labor government forecast accuracy versus actual outcomes, limiting the ability to assess whether Labor forecasts were similarly optimistic or more accurate.
While Labor's actual wage outcomes since 2022 have exceeded Coalition-era performance, this reflects real economic outcomes rather than forecast accuracy.
**Phillips Curve Complexity:** The claim assumes traditional economic theory (the Phillips Curve, which posits that wage growth requires falling unemployment) means forecasting wage growth without unemployment decline is straightforwardly irrational.
**The Guardian (Original Source):** The Guardian is a mainstream, reputable international news organization with editorial standards, though with a center-left editorial perspective.
The specific 2019 budget article focused on exposing what it characterized as unrealistic budget assumptions, consistent with the publication's broader coverage approach [4].
The article appears to have been based on comparative analysis of budget forecasts versus actual outcomes.
**Supporting Sources Verification:** The core claims were independently verified by multiple reputable sources:
- **The Australia Institute's Centre for Future Work** [1] - established economic research organization
- **Australian Council of Trade Unions** [3] - stakeholder organization with direct interest in wage data
- **Crikey** [2] - Australian political and economics commentary publication
- **International sources** (San Francisco Federal Reserve, IMF) [5][6][7] provide corroborating economic theory and evidence
These independent sources confirm the Guardian article's basic assertion without relying on the Guardian itself as evidence.

**Did Labor do something similar?**
Search conducted: "Labor government wage growth forecasts accuracy, Labor vs Coalition wage predictions, Australian Treasury forecasts Labor government 2010-2013"
**Finding:** Unlike the Coalition comparison where there is substantial independent documentation of systematic forecast failure, comprehensive comparative analysis of Labor government wage forecasting accuracy from the 2010-2013 period is not readily available in public sources.
* * * *
The Labor government period (2007-2013) concluded over a decade ago, and systematic retrospective analysis of its wage forecasts versus actuals does not appear to be as extensively documented as Coalition performance.
**Partial Evidence:** Real wage growth during Labor's 2007-2013 period reportedly performed better than the Coalition era, but this reflects actual economic conditions (pre-GFC and post-GFC contexts) rather than forecast accuracy [8].
**Assessment:** This element of the comparison cannot be fully resolved without access to Labor Treasury forecasts from 2010-2013 and systematic comparison to actual outcomes.
The claim's implicit comparison (that Coalition forecasts were distinctively problematic) is supported, but whether Labor would have been better cannot be definitively answered from available sources.

**Government Perspective on Wage Growth:**
The Coalition government maintained that wages would grow as labor market conditions tightened and productivity improved [1].
However, this perspective failed to account for structural changes in labor markets that decoupled unemployment from wage growth.
**Why This Matters - Not Just Partisan Critique:**
This pattern of optimistic wage forecasts was not unique to budget presentation.
The fact that actual wages remained stagnant while unemployment fell contradicted the forecast assumptions.
**Did Labor Face Similar Challenges?**
While comparative Labor forecasting data is limited, Labor governments historically have also made optimistic economic forecasts.
The difference appears to be that actual wage outcomes during the subsequent Labor administration (2022-present) exceeded Coalition-era performance, though this reflects economic conditions rather than forecast superiority [3].
**Key Context:** The systematic disconnect between Coalition wage forecasts and actual outcomes was not anomalous to one budget cycle—it repeated year after year.
The factual claim that Coalition governments consistently forecast optimistic wage growth that failed to materialize is **TRUE and well-documented** [1][2][3].
While the traditional Phillips Curve framework makes such forecasts appear illogical, modern labor economics shows that wage-unemployment relationship is weaker than classical theory suggests [5][6][7].
The forecasts were not merely "irrational"—they were failures to account for documented structural wage suppression, weak worker bargaining power, and the historical reality that Australia's wage-unemployment relationship had decoupled.
