Bad weather and the coronavirus have hit Dreamworld visitor numbers and publication next week of the Queensland Coroner's report into the 2016 fatal accident will ensure the troubled theme park does not break even this year, Dreamworld owner Ardent Leisure said on Friday.

The company also declined to say whether Dreamworld – still struggling to recover from the Thunder River Rapids accident that killed four people in October 2016 – would become profitable next year, even as it reported revenue at the Gold Coast park rose almost 5 per cent in the first half.
