“April was unseasonably warm and dry across Australia.”
SINGLE SOURCE
One web result ('Why has this autumn been so hot and dry?') explicitly supports the claim that April was warm and dry, mentioning NSW's second-driest April and Bairnsdale's low rainfall. However, other results discuss different years or general climate, and no second independent source corroborates this specific April event.

“Temperatures were above average or very much above average for most of the country [in April].”
DISPUTED
Evidence is contradictory. One source ('Why has this autumn been so hot and dry?') states temperatures were above average for most of the country. However, a Bureau of Meteorology source for April 2026 states temperatures were below average in the north and west coast, and a Weatherzone source states April 2024 was the first cooler-than-average April since 2015.
