Australian News Today (ANT) October 7, 2026 – Deloitte has issued a sombre assessment of Australia’s economic prospects, arguing that the period of exceptional growth enjoyed by the country from the 1990s until the Covid-19 pandemic has effectively come to an end. The consulting firm’s latest quarterly Business Outlook begins with the blunt line, “It was good while it lasted,” before outlining a deterioration in Australia’s economic performance over time. Deloitte expects real GDP growth of 1.5 per cent in the current financial year, compared with 2.3 per cent in the previous year, while its forecast for the following financial year has been cut from 1.9 per cent to 1.7 per cent.

The report places particular emphasis on productivity and the changing contribution of immigration to economic growth. Deloitte argues that immigration has increasingly become a substitute for productivity gains, highlighting a structural challenge for Australia’s economy rather than presenting the slowdown as a temporary fluctuation.

What does Deloitte’s latest economic outlook say about Australia?

Deloitte’s quarterly Business Outlook presents a significantly weaker growth picture than the performance Australia recorded during much of the period beginning in the 1990s.

According to the report, the country’s record-breaking growth has “deteriorated over time”. The assessment suggests that the economic model that supported Australia’s strong performance for decades is no longer producing the same results.

The immediate figures underline the change.

Deloitte expects real gross domestic product to expand by 1.5 per cent during the current financial year. That represents a substantial reduction from the 2.3 per cent growth recorded in the previous financial year.

The consultancy has also revised its forecast for the financial year that follows. It previously expected growth of 1.9 per cent, but that projection has now been reduced to 1.7 per cent.

These figures do not indicate an economy that has stopped growing. Instead, they point to a prolonged period of relatively weak expansion and a widening concern about the forces supporting future growth.

The significance of the Deloitte assessment is therefore broader than the latest GDP forecast. Its central argument concerns the quality and sustainability of Australia’s economic growth.

Why does Deloitte say Australia’s strong growth has deteriorated?

The report identifies productivity as a central issue.

As reported in the supplied coverage of Deloitte’s Business Outlook, the consulting firm says immigration has increasingly become a substitute for productivity gains. In other words, population growth has helped support overall economic activity at a time when improvements in productivity have become less capable of driving stronger growth.

This distinction is important when interpreting GDP figures.

An economy can expand because it has more people participating in economic activity, while the amount produced by each worker or each hour worked remains comparatively weak. Such growth can increase the overall size of the economy without delivering the same improvement in economic performance per person.

Deloitte’s assessment indicates that this dynamic has become increasingly important in Australia.

The consultancy’s criticism is consequently focused on a structural relationship between population growth and productivity. Rather than relying primarily on improvements in how efficiently the economy produces goods and services, Australia has increasingly depended on additional population to support economic expansion.

The report’s opening phrase, “It was good while it lasted,” reflects the scale of the change identified by Deloitte.

How much has Deloitte downgraded Australia’s GDP growth forecast?

Deloitte has lowered its growth expectations for both the current and following financial years.

For the current financial year, the consultancy expects real GDP growth of 1.5 per cent, compared with 2.3 per cent in the previous financial year.

That represents a decline of 0.8 percentage points between the two annual growth rates.

Deloitte has also reduced its forecast for the following financial year. The previous projection was 1.9 per cent, but the latest Business Outlook puts expected growth at 1.7 per cent.

The downward revision is smaller in numerical terms than the year-to-year slowdown, but it is significant because it indicates that Deloitte does not expect the weaker performance to disappear immediately.

The figures therefore describe two related developments: an immediate slowing of economic growth and a more cautious assessment of Australia’s medium-term growth prospects.

What happened to Australia’s economic performance after the 1990s?

Australia experienced a prolonged period of strong economic growth beginning in the 1990s and continuing until the disruption associated with Covid-19.

The period became notable for Australia’s ability to sustain economic expansion over an extended period. Strong population growth, international trade and other economic factors contributed to the country’s performance.

Deloitte’s latest report argues that this exceptional period has now ended.

The report describes the previous record of growth as having “deteriorated over time”. That wording places the current slowdown within a longer-term trend rather than presenting it solely as a consequence of recent economic conditions.

The Covid-19 pandemic was an important dividing point, but Deloitte’s assessment indicates that the deterioration in underlying economic performance extends beyond the immediate effects of the pandemic.

The report’s argument is that the fundamentals supporting Australia’s previous growth performance have weakened.

Why is productivity important to Australia’s economic outlook?

Productivity is important because it affects how much economic output can be generated from existing resources.

When productivity rises, businesses and workers can produce more from the same amount of labour, capital or other inputs. Sustained productivity improvements can therefore support higher economic growth without requiring equivalent increases in the size of the population.

Deloitte’s concern is that Australia has increasingly relied on population growth instead.

The report’s observation that immigration has become a substitute for productivity gains does not mean immigration itself is identified as the sole cause of Australia’s weaker economic performance. Rather, it highlights the relationship between population growth and the underlying productivity of the economy.

The distinction is particularly relevant when considering GDP.

Total GDP can increase as the population expands, even if output per person grows slowly. If productivity remains weak, however, maintaining strong overall growth becomes increasingly dependent on adding more people to the economy.

Deloitte’s latest assessment suggests that this model is becoming less effective.

What does the Deloitte forecast mean for Australia’s economic growth?

The immediate implication is that Australia is entering a period of slower economic expansion than it experienced during its strongest decades.

The 1.5 per cent real GDP forecast for the current financial year represents a clear reduction from the previous year’s 2.3 per cent growth.

The subsequent forecast of 1.7 per cent indicates that Deloitte expects some improvement after the current financial year, but not a return to the previously forecast 1.9 per cent rate.

The forecasts therefore suggest that stronger growth is not expected to return quickly.

At the same time, the figures should not be interpreted as a forecast of economic contraction. Deloitte continues to expect positive GDP growth. The concern instead centres on the relatively modest pace of expansion and the structural factors limiting Australia’s ability to achieve stronger results.

That distinction is important for businesses, workers and policymakers assessing the report.

What does Deloitte’s assessment mean for Australia’s productivity challenge?

The productivity issue identified by Deloitte is likely to remain central to discussions about Australia’s longer-term economic performance.

If immigration and population growth are doing more of the work of supporting overall GDP, while productivity growth remains weak, the economy may struggle to reproduce the rates of expansion seen during the earlier period highlighted in the report.

The consultancy’s assessment therefore places emphasis on the underlying sources of economic growth.

The report does not simply state that Australia’s GDP growth is slowing. It connects the slowdown with a deterioration in the country’s economic performance over time and specifically identifies productivity as an area of concern.

That makes the Business Outlook relevant beyond the immediate GDP figures.

The central question is whether Australia can generate stronger growth through increased productivity rather than depending increasingly on population expansion.

How does immigration feature in Deloitte’s economic assessment?

Immigration is a key element of the report because Deloitte links Australia’s population growth with the country’s broader economic performance.

According to the Business Outlook, immigration has increasingly acted as a substitute for productivity gains.

This observation places population growth within the wider debate over how Australia should sustain economic expansion.

Immigration can increase the number of people working and consuming within an economy, thereby contributing to total economic activity. But Deloitte’s assessment indicates that population expansion does not automatically resolve the underlying productivity problem.

The report’s concern is therefore about the balance between the two.

If economic growth depends increasingly on having more people rather than producing more efficiently, the overall growth rate may become less reflective of improvements in productivity.

Deloitte’s latest forecast suggests that Australia faces this challenge at a time when overall GDP growth is already slowing.

What could the weaker growth forecast mean for Australian businesses?

For Australian businesses, slower GDP growth generally means a weaker overall environment for expansion than during periods of stronger economic activity.

The Deloitte figures point towards a period in which economic growth is expected to remain positive but comparatively subdued.

Businesses may therefore face an environment where increases in overall demand are less pronounced than during Australia’s stronger growth years.

The productivity issue also has a direct relevance to businesses. If productivity improvements remain insufficient, companies and the wider economy may find it harder to generate higher output without additional labour and population growth.

Deloitte’s report consequently raises a longer-term issue for Australia’s business environment: whether economic expansion can become more closely linked to productivity improvements.

The available material does not establish specific consequences for individual industries or companies, so those effects should not be assumed from the headline forecasts alone.

What is the wider significance of Deloitte’s warning?

The wider significance of the report lies in its description of a change in Australia’s economic trajectory.

For decades, the country was able to maintain strong economic growth, with the period from the 1990s until Covid-19 representing a particularly notable phase.

Deloitte’s assessment says that this performance has deteriorated over time.

The combination of slower GDP growth, downgraded forecasts and concerns about productivity provides the basis for the consultancy’s more pessimistic outlook.

The wording of the report is particularly notable because it does not present the current slowdown simply as another stage in the economic cycle. Its argument is focused on the underlying drivers of growth and the changing role of immigration.

That makes the report a warning about Australia’s future growth capacity rather than merely a forecast for the next financial year.

What is the background to Australia’s changing growth outlook?

Australia’s economy experienced a prolonged period of strong growth from the 1990s through to the Covid-19 period. That performance established a benchmark against which the country’s current economic position is being assessed.

Over time, however, the factors supporting that performance have weakened.

The latest Deloitte Business Outlook identifies declining productivity growth as a central part of that deterioration and argues that immigration has increasingly helped compensate for weaker productivity gains.

The Covid-19 pandemic also marked a major disruption to economic activity, although Deloitte’s latest assessment places the current problem within a broader deterioration over time rather than attributing it solely to the pandemic.

The latest forecasts provide a numerical illustration of that change. Real GDP growth is expected to fall from 2.3 per cent in the previous financial year to 1.5 per cent in the current financial year, while growth for the following financial year has been revised down from 1.9 per cent to 1.7 per cent.

What can Australia expect from the Deloitte forecast?

The available Deloitte figures indicate that Australia is likely to face a period of slower economic growth, with the consultancy expecting positive but subdued GDP expansion over the next two financial years.

For Australian businesses and economic policymakers, the most important issue is the productivity challenge identified in the report. If productivity growth remains weak, Australia’s ability to reproduce the exceptional growth rates experienced from the 1990s until Covid-19 may remain constrained.

Deloitte’s forecast does not establish that Australia’s economy will contract, nor does it provide a basis for predicting a specific outcome for individual businesses or households. Its assessment instead points to a slower-growth environment and highlights the changing balance between population growth and productivity.
