A.1Research question and inquiry
Excellent
Criteria Feedback
- You establish a clear, focused research question that is tightly linked to a specific local environmental issue.
- Your background shows strong contextual understanding of the nullah and why dissolved oxygen is a relevant indicator.
- You acknowledge a potential confounding factor rather than oversimplifying the system.
- You could explain more explicitly why the five sampling points are sufficient to capture the water-quality gradient.
- The inquiry would be slightly stronger if you linked the research design more clearly to how the chosen sites represent the whole system.

B.1Strategy
Excellent
Criteria Feedback
- You identify an existing local strategy that directly addresses the environmental issue in the investigation.
- You explain a real tension between perspectives, especially between enforcement/revitalisation aims and residents’ lived experience of pollution and odour.
- You support the strategy with specific evidence rather than keeping the discussion abstract.
- The discussion would be stronger if it explained more clearly why surveillance in one area may not address other dumping routes or diffuse pollution.
- You could develop the tension further by comparing the strategy’s benefits for the government with its limitations for local environmental recovery.
