Contact Honan Insurance Group citing the date, time, cause and location of the loss.
Take photos of damages.
Obtain identification of all civil authorities involved such as fire, police, health department, building inspector, etc.
Keep damaged items safely for assessment.
Retain all invoices, time sheets etc, to ensure all costs are captured and attributable to the loss and to prevent an overlapping of normal costs with these expenditures.
If you are making a business insurance claim have your ABN and GST information handy (if applicable).
