Exact syllabus points covered
- Explain the methods of protection employed by nations, and construct supply and demand diagrams to demonstrate the effect of methods of trade protection, including tariffs and non-tariff barriers (e.g. subsidies, quotas and bureaucratic requirements).
- Analyse and evaluate the economic arguments for and against protectionism and trade liberalisation responses from different viewpoints using economic criteria (e.g. economic efficiency, economic growth, living standards or resource allocation) to make a decision about the past, present or future regarding the relative merits of trade policy alternatives.
- Explain bilateral, regional and multilateral trade agreements that involve Australia.
- Explain the contemporary role of 'free trade' agreements and their impact on Australia's international trade, including trade creation and trade diversion.
- Analyse and evaluate the economic outcomes of international trading bloc agreements (e.g. Australia-New Zealand Closer Economic Relations Trade Agreement (CER), European Union (EU), North American Free Trade Agreement (NAFTA), ASEAN-Australia-New Zealand Free Trade Agreement (AANZFTA)) on Australian economic growth, and decide on the net benefits using economic criteria, e.g. economic efficiency, economic growth, living standards or resource allocation.
- Create responses that communicate economic meaning using data, information, graphs and diagrams in paragraphs and extended responses to suit the intended purpose.
Trade protection is government action that gives domestic producers an advantage over foreign producers. It can be direct, such as a tariff, or indirect, such as a regulation that makes imported goods harder to sell.
Trade agreements do the opposite: they reduce barriers between countries so trade can expand.
Methods of protection
| Method | How it works | Main effect | |---|---|---| | Tariff | A tax on imports | Raises the domestic price of imported goods | | Quota | A limit on the quantity imported | Restricts supply and can raise price | | Subsidy | Government payment to domestic producers | Lowers domestic producers' costs | | Bureaucratic requirements | Rules, paperwork or standards that slow imports | Raises the cost or difficulty of importing | | Local content rules | Requires a share of production to be local | Supports domestic input suppliers |
Tariffs are the easiest to draw. A tariff raises the import price, reducing quantity demanded, increasing domestic production, reducing imports and creating government revenue. It also creates efficiency losses because consumers pay more and resources are pulled into production that may be less efficient than overseas production.

Arguments for protection
Governments may use protection to:
- protect employment in vulnerable industries
- support infant industries until they become competitive
- prevent dumping, where imports are sold below cost or below home-market prices
- protect national security industries
- maintain regional communities
- reduce reliance on unstable overseas supply chains
These arguments are strongest when the policy targets a temporary problem, protects a genuinely strategic industry, or gives firms time to become internationally competitive.
Arguments against protection
Protection can:
- raise consumer prices
- reduce allocative efficiency
- reduce pressure for firms to innovate
- invite retaliation from trading partners
- increase production costs for firms that use imported inputs
- shift resources toward industries where Australia has no comparative advantage
The strongest evaluation usually recognises short-run and long-run effects. A tariff may protect jobs now, but weaken productivity and living standards later if it preserves inefficient production.
Trade agreements
Trade agreements reduce barriers between countries. They can be:
- bilateral: between two economies
- regional: between a group in a region
- multilateral: involving many economies
Australia is involved in agreements such as the Australia-New Zealand Closer Economic Relations Trade Agreement, the ASEAN-Australia-New Zealand Free Trade Area, and other bilateral and regional arrangements.
Trade creation and trade diversion
Trade creation occurs when an agreement shifts consumption from higher-cost domestic production to lower-cost partner-country imports. This improves efficiency.
Trade diversion occurs when an agreement shifts consumption from a lower-cost non-member country to a higher-cost member country because the member receives preferential access. This can reduce global efficiency.
| Concept | Direction of shift | Efficiency effect | |---|---|---| | Trade creation | High-cost domestic producer to lower-cost partner producer | Usually positive | | Trade diversion | Lower-cost outsider to higher-cost partner producer | Often negative |
Evaluating trade policy
Use criteria from the question. If the criterion is living standards, consider consumer prices, employment, incomes and access to goods. If the criterion is efficiency, focus on resource allocation, productivity and deadweight losses. If the criterion is economic growth, consider exports, investment, output and long-run competitiveness.
