Local Environmental Conditions
The nearest stream or river hosts wattle and casuarina, two of the most allergenic early-season trees; this sits near this part of town. This area, within the neighborhood's edge, has forest where plane tree and eucalypt make up much of the canopy, driving spring pollen counts.
In Research, temperatures climbing to 10.8°C by September likely mark the start of the main pollen release, with humidity around 76% helping keep counts airborne. Warmer conditions by December (17.9°C, 65% humidity) sustain grass pollen through the season, before rainfall of 54mm in March and cooling toward 7.9°C in June bring the season to a close.

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. |
