Local Environmental Conditions
Nearby, in the wider area, a waterway supports wattle and casuarina along its bank, both strongly allergenic wind-pollinated species. Located nearby, this area has this patch of forest is largely plane tree and eucalypt, a pairing known for heavy spring pollen output. Actual counts still shift year to year with temperature, rainfall, and prevailing wind.
Along the waterway, wattle and casuarina release pollen first, hitting its peak before most trees have even budded, around late winter into September. Plane tree and eucalypt nearby take over the pollen calendar through mid-spring, typically landing in October and November. Grass pollen takes over next, building to a peak around December, before plantain and weed pollen takes center stage across mid-February into April.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
