Flood check, Idalia

Has Idalia flooded?

No historic flood extent has been mapped for the Idalia area by the state or the council.

  • Townsville City has been disaster-activated for 22 flood, storm or cyclone events since 2008 — most recently Queensland Monsoon Trough, Cyclone Koji, Cyclone Narelle and Severe Weather 24 December 2025 - 24 April 2026.
  • Nearest flood-warning gauge: Cluden Alert, Ross basin — 2 km from the centre of Idalia.

An extent is the official maximum-inundation line for that event. "Reaches into Idalia" means the mapped line crosses the suburb boundary — most of the suburb may be well clear of it, which is why the address check below matters. Events are listed only where the state or council has mapped this area.
