When is grass pollen season in Australia?
In Melbourne, Sydney, Adelaide, Perth, Canberra and Hobart, grass pollen starts in September, is high in October and peaks in November and December, before tailing off in January. From Brisbane north, the summer grasses keep it going from November to February and into March. Cypress pine (Callitris) comes earlier, in late winter and spring, peaking in September.

A map of the whole country. The level in each city at a glance, plus air quality for the same place.
