The disturbance that created the liability, the approved prescription that treats it, the campaigns and work packages that deliver it, and the hold-point inspections and materials that prove it was done to specification

The closure domain as the operational unit — its disturbed, available, rehabilitated and certified hectares tracked separately, its land-availability history, and the post-mining land uses agreed for it

Versioned, measurable definitions of "done" — the plan-level criterion, its domain-specific targets, and the dated assessments that decide whether it is met, at risk or not met

Monitoring programs and their scheduled parameters by location, the field and laboratory events that satisfy them, and the validated results with target ranges and exceedance flags

Progressive certification applications and the criteria each one carries, whole-of-site relinquishment and its per-domain readiness, and the periodic and triggered reviews of the closure plan

The closure risk register with inherent and residual rating, the findings raised by exceedances and failed assessments, and the corrective actions tracked to verified closeout

Regulators, landholders, Traditional Owners and community stakeholders, the engagement record with concerns and outcomes, and the commitments made to them tracked to delivery evidence

Versioned closure cost estimates by class with escalation and contingency, their line items by domain and category, and the actual expenditure reconciled against them

Where the obligation came from — authority, source document and requirement — and how the closure plan answers it, with its assumptions, objectives and requirement links

Operator and contractor organisations, the people accountable for domains, plans and assessments, the mine site and its nested spatial areas

Controlled documents behind plans and prescriptions, the photographs, surveys, laboratory results and certificates that evidence completion, and the recorded approval decisions
