Insurer Suncorp has fielded about 3,750 claims from customers following the heavy rain and flash flooding that continues to plague large parts of Victoria.
The claims are mostly for property damage since winds of up to 125km/h and heavy rain lashed the state from Wednesday night. Two people have died.
The insurer, which has brands AAMI, Apia and GIO, said claim numbers were expected to rise for weeks.
Suncorp chief executive Steve Johnston said staff were in Traralgon and meeting affected customers.
Traralgon, in the Latrobe Valley, is one of the hardest-hit areas.
Suncorp shares were higher by 0.62 per cent to $11.29 at 1143 AEST.
