The Victorian Bushfires Royal Commission has uncovered widespread opposition to the fire services levy (FSL), according to the interim report it released last week.

Of the 65 insurance-related submissions tabled, most called for reform of the levy, which is charged on premiums in NSW, Victoria and Tasmania.

"The majority of submissions about insurance issues related to dissatisfaction with the fire services levy being part of voluntary insurance," the report said.

CGU called for a wider funding base recognising fire services as a public good, while Suncorp described the current system as "inequitable".

RACV Insurance said the "fire services levy is a major contributor to non-insurance and under-insurance".

The royal commission is yet to address insurance matters but will do so before hearings conclude on May 13 of next year. A final report is due in July of next year.

Insurers received around 10,040 claims following the devastating February bushfires, with insured losses of $1.07 billion. An estimated 30% of homes were not insured.

Last week's interim report contains 51 recommendations intended to improve emergency response procedures.

They include vastly improved community warning systems, streamlined emergency service procedures and better community refuge resources.
