TRMM TMI data show heavy rain over the states of South Australia and New South Wales on February 9-12. The northwest part of South Australia experienced flooding begining on February 11 after receiving over 15cm of rain in two days. Flooding was also reported in the adjacent Northern Territory in the Ayers Rock area along the Finke, Hugh and Palmer rivers.

Starting on February 13 smaller areas of heavy rain can be seen over various parts of Queensland including the Great Dividing Range, York Peninsula and the coastal area near the Great Barrier Reef. Flooding was first reported in coastal Queensland in the town of Giru along the Haughton River on February 18; the next day there were submerged train lines near nearby Townsville. The runoff from much of this precipitation flows into the Great Artesian Basin in central inland Queensland. On February 17-19 and the 22nd TRMM TMI data show heavy rain directly over the main area of flooding in Queensland; this area was bounded by the towns of Richmond, Hughenden, Muttaburra, Longreach and Winton. On February 23 there were reports that flooding of the Diamantina River had totally isolated the town of Winton; farther east along the Thomson River, over 60 people were evacuated in the town of Longreach.

By February 24 a third of the state of Queensland was under water, the water forming a giant lake over the Queensland channel country. Flooding also continued in the Northern Territory and spread into New South Wales state.On February 26 Cyclone Steve can be seen approaching the coastal city of Cairns in the TRMM TMI data On the 27th it came ashore in northern Queensland and caused more flooding along the coast. Residents of the town of Mareeba had to be evacuated when the Barron River burst its banks. The water from Queensland moved downriver in to New South Wales where the Broken Hill area was flooded by the Paroo River on February 28.
