2026 HSC Economics exam: What to learn from last year’s mistakes
Hi all, in preparation for the upcoming exam, here's what to learn from last year's mistakes.
Exam: Tuesday 27 October 2026, 1:55 pm to 5:00 pm. All times are NSW local time.
The 2025 exam was 100 marks: 20 multiple choice, 40 short answer and two 20-mark extended responses.
The useful questions here are Q21b (3 marks), Q22a–c (10), Q23b–d (8), Q25 (20) and Q27 (20).
NESA's feedback identifies the mistakes but does not give question averages or percentages scoring zero.
1. Q21b: Income alone does not measure quality of life
Where students went wrong
Students described income without explaining what it leaves out. Some confused the components of the Human Development Index.
What they should have done
Explain the limitation and its consequence. An average income figure can rise while gains go mainly to high-income households, so it can hide unequal living standards. Income also does not directly measure access to education or health outcomes. HDI combines health, education and income dimensions; it is not simply another name for income per person.
2. Q22a–b: Read the currency movement before explaining it
Where students went wrong
Students missed the depreciation or supplied a domestic cause when Q22a required a global factor. Q22b answers confused direct and indirect intervention.
What they should have done
The diagram showed lower demand for AUD and a depreciation. A global fall in demand for Australian exports can reduce demand for AUD to pay for those exports. For direct intervention to support the dollar, the RBA buys AUD and sells foreign currency. That is different from an interest-rate change influencing capital flows.
3. Q22c: Depreciation affects different firms differently
Where students went wrong
Some answers treated depreciation as universally good or bad for Australian businesses.
What they should have done
Exporters can become more price-competitive for overseas buyers. Import-competing businesses can benefit when foreign alternatives become more expensive. But firms buying imported inputs face higher AUD costs, which can squeeze margins or push up prices. A business can face both effects. Explain the balance using its sales and cost exposure rather than assigning one outcome to every firm.
4. Q23b–d: Participation, unemployment and NAIRU are not interchangeable
Where students went wrong
Students explained rising unemployment when asked about falling participation, ignored the data, or used demand stimulus as though it necessarily lowered NAIRU.
What they should have done
Participation falls when people leave the labour force relative to the working-age population. A discouraged job seeker who stops actively seeking work is one possible explanation.
In Year 2, unemployment was 5.9% against a 5% NAIRU, a gap of 0.9 percentage points consistent with cyclical unemployment.
For Q23d, explain two policies that address structural or frictional unemployment. Retraining can reduce skills mismatch; improved job matching can shorten the search between jobs. Explain how each changes the underlying labour-market problem. Extra demand alone does not establish a lower NAIRU.
5. Q25: Explain the whole balance of payments
Where students went wrong
Students wrote mainly about the current account, confused a trend with its cause, or failed to connect financial flows with primary income.
What they should have done
Identify what changed over time and explain why. For instance, foreign borrowing is recorded through financial transactions, while the later interest payments affect primary income. Keep transactions and income flows distinct. Use evidence on the relevant components instead of treating a movement in the trade balance as an explanation of every balance-of-payments movement.
6. Q27: Explain why the objectives conflict
Where students went wrong
Students asserted a trade-off without identifying its cause or applying policy and Australian evidence.
What they should have done
Explain the mechanism. Stronger aggregate demand can increase output and employment, but near capacity it can also raise inflation pressure. Show why the policy advances one objective and makes another harder to achieve in those conditions. If you use a Phillips curve or PPC, explain the movement and assumptions. A diagram cannot replace the analysis.
