Flood risk
NSW SES · Georges River catchment · updated September 2026How much of this suburb sits inside NSW SES's modelled flood extents for the Georges River catchment? These are predicted extents at different probability levels, not a record of floods that have actually happened here.
Modelled flood extents
NSW SES models three flood-extent scenarios for the Georges River catchment, from the standard flood-planning benchmark to a worst-case extent. None of these say a flood has actually occurred — they mark land that modelling puts inside each scenario’s reach.
- 1% AEP (1-in-100-year): the standard NSW flood-planning benchmark — a flood with a 1-in-100 chance of being reached or exceeded in any given year.
- Flood potential: a broader strategic extent of land that could be affected under any of the modelled flood scenarios.
- Probable Maximum Flood: the most severe flood NSW SES models as physically possible for this catchment — rare, but the outer limit of what's possible.
NSW SES's Georges River flood modelling puts about 30% of Mortdale - Oatley inside the 1% AEP (1-in-100-year) flood extent — the standard NSW flood-planning benchmark. In NSW SES's worst-case Probable Maximum Flood scenario, that grows to about 37% of the suburb.
This data only covers the Georges River catchment (southern and south-western Sydney) — NSW SES hasn’t published an equivalent modelled-extent map for Sydney’s other catchments, and a suburb rollup can’t tell you about an individual property.
