房屋保险的GST liability是什么意思？

家在澳洲

新买的house insurance，这几天收到保险公司发来一个表格是关于GST liability的，不明白什么意思，想请教大家。。。表格上写的是：

xxx(the insurance company) wants you to avoid having a GST liability on any claim we settle for you. You will have a liability if you are (or someone else is) entitled to a GST credit on this premium and you've either:

Not told us; or
Understated that entitlement.

The information we hold about your policy tells us that you are (or someone else is) entitled to an input tax credit on this premium of 0%.

然后下面就是说如果不是0％的话，就填表告诉他们是百分之几。。。不太明白这个是什么意思。。。

谢谢大家⋯⋯

如果你的房子是自用的话，不用理会这个
如果是的房子用来做公司办公室，你注册了gst,你可以claim 1/11 gst credit
