A bushfire is a wildfire that occurs in the forests, scrubs, woodlands or grasslands of Australia or New Zealand.

A bushfire is a wildfire that occurs in the bush (collective term for forest, scrub, woodland or grassland of Australia, New Zealand, New Caledonia). In southeast Australia, bushfires tend to be most common and most severe during summer and autumn, in drought years, and particularly in El Niño years. In the north of Australia, bushfires usually occur during winter (the dry season), and fire severity tends to be more associated with seasonal growth patterns.
