These jobs were mainly for leaky roofs and fallen trees and were focused in areas like Townsville, which had more than 25 callouts since Wednesday morning.
Cairns and surrounding areas also received between 10-15 jobs in the same time period.
It is expected areas like Mackay and Rockhampton will be the focus for SES volunteers today.
While the Queensland Fire and Rescue Service (QFRS) was not called to any swift water rescues overnight, residents are reminded "If it's flooded, forget it". Under no circumstances should people risk driving or walking through floodwaters.
The Bureau of Meteorology (BoM) has issued severe weather warnings for excessive winds and heavy rainfall along the Queensland coast from the Northern Tropical Coast and Tablelands down to Gladstone and Bundaberg. Flood warnings are current for a number of rivers and streams in these districts.
