Insurance for personal items

Hi 

We are shortly relocating to Maputo and leaving all of our house contents in storage in Australia, however as we will be working as Fly in / fly out employment every 8 weeks we are wondering what everyone does about making sure that their personal possessions are covered by insurance. Such items are computers, jewellery , watches computers and camera equipment. Our company provides us with medical insurance but I am not sure what to do about the other. At the moment we do not have insurance in Australia as we have been living in Cape Town but Australia according to our employment and Visas will now be our place of residence. anyone out there have any experience in this, and I wonder how it goes if its covered in Australia and how good are they at paying out   Thanks Deborah
