Join Roy Morgan CEO Michele Levine in our latest webinar to discover:
- Banks: Commonwealth Bank leads Bendigo Bank in the trust rankings for the first time — with movement across the majors that changes the conversation for ANZ, NAB and Westpac.
- Supermarkets: Woolworths vs Coles — the trust gap compresses even as distrust remains elevated; we’ll show which way each brand has moved and why it matters for pricing power.
- Airlines: Qantas’ trust recovery is positive but asymmetric;
- Virgin Australia holds the advantage — we’ll show how far the gap has moved.
- Health insurance: Medibank’s lingering distrust vs the trajectories for Bupa and nib — who’s rebuilding, who’s stuck.
- Energy: Trust movements for AGL, Origin and EnergyAustralia— and who’s winning.

Margin of Error
The margin of error to be allowed for in any estimate depends mainly on the number of interviews on which it is based. Margin of error gives indications of the likely range within which estimates would be 95% likely to fall, expressed as the number of percentage points above or below the actual estimate. Allowance for design effects (such as stratification and weighting) should be made as appropriate.
