I'm looking to get my first SUP and store it in the backyard of my unit. The driveway is not secure so I want to insure it for theft.

Do I just include it as a portable item on my home and contents insurance ?

Any tips appreciated.

Cheers,

My home and contents is with NRMA and I have it listed as a portable item. I queried as to whether it has to be locked onto the car to be covered, they said no and that if someone removed it from the car with only straps it was covered. I'd say if it was in the back yard and someone came in and took it you would be covered.

I have mine insured and if it is outside at your house it is covered and also as above I have it listed as a portable item and all covered

Yes household insurance with designated items listed as portable like mbuzz says.

Ring up the insurance company and pretend u had one stolen .
free board for you minus excess

I have two boards insured on my Home/Contents and paid a little extra to have them itemised with their purchase prices. They were covered for their full purchase amounts when stolen off my car outside the house before going paddling one morning when I popped back in for a coffee. Thankfully they were located 8 days later. I can highly recommend AAMI for this, and I don't recommend insurers often! I'm located in Tassie.
Cheers and good luck.
