The concluding evaluative question for Unit 4, Area 2 asks students to assess Australia’s overall impact on regional political order. This requires applying the concepts of stability and change across Australia’s full range of actions.
Political stability in the Indo-Pacific means:
- Maintenance of a rules-based international order (UNCLOS, UN Charter, WTO rules)
- Absence of major interstate conflict
- Predictable, cooperative state behaviour
- Continued functioning of regional institutions (ASEAN, PIF, EAS)
Political change means:
- Shifts in the distribution of power (military build-up, new alliances, rising states)
- Changes to regional institutions or norms
- New alignments or coalitions forming
- The replacement or erosion of one regional order by another
Australia is a middle power: its actions matter for regional order, but they are not determinative. Australia acts within structural constraints set by the US-China strategic competition.
1. AUKUS and deterrence
- The AUKUS nuclear-powered submarine capability (when delivered) is intended to contribute to deterrence against Chinese coercion in the region, particularly in the Taiwan Strait and South China Sea scenarios
- Stability argument: deterrence theory holds that credible capability prevents war; Australian submarines extend the deterrent against coercive action
- Counter-argument: AUKUS accelerated arms race dynamics; China, Indonesia, and Malaysia expressed concern that it will increase tensions and militarise the region further
2. Multilateral institution engagement
- Australia’s active participation in ASEAN forums, PIF, G20, and QUAD helps maintain institutional frameworks that manage disputes and coordinate responses
- Support for UNCLOS contributes to rules-based maritime order
- Australia’s climate financing to the Pacific (post-2022) stabilised a relationship that had been deteriorating, reducing the risk of Pacific states aligning with China for lack of alternatives
3. Trade and economic engagement
- Australia’s economic integration with the region (RCEP, bilateral FTAs) creates mutual economic stakes in stability
- Australian iron ore, LNG, and coal are critical inputs for Japan, South Korea, and China; this interdependence moderates conflict dynamics
4. Pacific security assistance
- The Pacific Maritime Security Programme (patrol boats, surveillance) contributes to maritime law enforcement across the Pacific, addressing illegal fishing, people-smuggling, and search and rescue
- Australia’s police missions in PNG, Solomon Islands, and Timor-Leste contribute to domestic stability in fragile states
1. AUKUS (change)
- AUKUS represents the most significant structural change to regional security arrangements since ANZUS (1951)
- It introduces nuclear-powered submarines into the Indo-Pacific, which China argues violates the spirit (though not the letter) of the NPT
- AUKUS has contributed to Japan’s own defence expansion (2% GDP target, offensive strike capability) and South Korea’s autonomous deterrence discussions — creating a broader regional military build-up
2. Departure from ASEAN centrality norms
- AUKUS and QUAD operate outside ASEAN-centred frameworks; they represent a shift toward minilateral security architectures that partially bypass ASEAN’s consensus-based, non-threatening approach
- This contributes to change in the regional institutional architecture — not necessarily negative, but structurally significant
3. Climate diplomacy
- Australia’s post-2022 climate commitments represent a positive change in its Pacific relationships; but the underlying issue (rising sea levels threatening Pacific statehood) is itself a driver of profound regional change that no Australian policy can prevent
4. Economic diversification
- Australia’s deliberate trade diversification away from China (India ECTA, CPTPP engagement, critical minerals partnerships with the US, EU, Japan) contributes to a gradual reshaping of regional economic architecture — reducing Chinese economic leverage, but also reducing the moderating influence of deep interdependence
| Domain | Stability | Change | Assessment |
|---|---|---|---|
| Security | Deterrence contribution; US alliance | AUKUS arms race dynamics; new military architecture | MIXED — stabilising to like-minded allies, destabilising to China and some ASEAN |
| Economic | Trade interdependence; aid | Diversification away from China | MIXED — reduces vulnerability but also reduces moderating links |
| Institutional | Multilateral engagement; UNCLOS support | QUAD/AUKUS outside ASEAN centrality | MIXED — sustains some institutions, bypasses others |
| Pacific/Regional governance | Pacific Step-Up; climate diplomacy (post-2022) | Competition dynamics in Pacific | MOSTLY STABILISING — improved relationships; but underlying structural tensions remain |
A strong exam response might conclude:
“Australia’s actions contribute to both stability and change in the Indo-Pacific. Australia’s multilateral engagement, Pacific security assistance, and support for UNCLOS-based maritime rules contribute to maintaining a rules-based regional order. However, AUKUS represents a significant structural change — introducing new military capabilities and an alternative security architecture that has accelerated arms race dynamics and strained relationships with Indonesia, Malaysia, and China. On balance, Australia’s actions stabilise the rules-based order as understood by Western-aligned states while simultaneously contributing to the structural change that China’s rise and US-China competition represent. Australia is both a manager of this transition and an active participant in it.”
KEY TAKEAWAY: Australia both stabilises and changes the Indo-Pacific regional order. The most intellectually honest analysis acknowledges that these processes occur simultaneously and that “stability” means different things from different vantage points — what Australia calls “maintaining the rules-based order” is what China calls “maintaining US hegemony.”
VCAA FOCUS: This KK is likely to appear in the extended response (Section C or equivalent) of the VCAA exam. It requires a structured argument with clear position, evidence from multiple domains, acknowledgement of counter-arguments, and a qualified conclusion. Practise writing 600–800 word responses to “To what extent has Australia contributed to political stability in the Indo-Pacific?” using the structure outlined above.
EXAM TIP: Use the VCAA rubric language: “to what extent” demands a qualified judgment, not a binary answer. Examiners reward students who say “Australia has contributed to stability in X ways, but also generated change/instability in Y ways, and on balance…” — not those who say simply “Australia contributes to stability.”
