Just check what sort of plastic they are made from. Normally the Australian ones are inferior to those from the US. The Australian plastic when broken will crack into sharp slithers - not recommended.
I found I was able to great a great screen form the US incl. shipping for the same price as a local brand. I am however usually keen to support local sellers but not in this case.
Do your research unless the safety aspect is not a consideration.
