Australia insurance required public liability please help!

Hi,

I am from Australia and I am having so much trouble finding insurance for booking.com for short term eg 2 x nights for bookings throughout a  whole year

I book out a single room to many different people each week and almost all year round. if I need to insure for more than 90 days  they wont insure me. I can pay a daily rate but that would mean doing a new insurance quote 2-3 times a week which is rediculous.

I am also on Stayz and Airbnb and they have 1 million public liability.

 I have had an insurer in the past year and they covered my house and contents that we live in plus the single room we rent out within our property to all our guests all year around including $10 million public liability insurance. The company no longer does it and now could only find one and they are $3k which is double the insurer I was with.

Can anyone suggest an australian broker or insurer that will not cost so much

 I dont understand why its so hard to get insurance especially when we live here while our guests are here so the guests dont party etc The chances are far higher for driving a car or climbing ladders etc its just a bedroom and public liability.

 Would really appreciate any suggestions

If I cannot insure I would have to give up booking.com and just remain with Airbnb and Stayz as I have worked too hard in my life to have someone sue me.

Thank you

Sherie
