BRISBANE, Australia — Military flights rushed today to restock an Australian city before it was cut off by floodwaters that have turned a huge swath of the Outback into a lake, while police confirmed two more deaths in the crisis.

Drenching rain that started before Christmas has flooded an area the size of France and Germany combined in northeastern Queensland state. Rivers are overflowing and at least 22 towns and cities in the farming region are inundated.

In the coastal city of Rockhampton, waters from the still-swelling Fitzroy River closed the airport and cut the main highway to the state capital of Brisbane. Scores of families abandoned their homes for relief centers on high ground. Today, floodwaters had inundated the last route into the city.
