FIXED! Australia post mod not working

Hi,
While setting a new install i can not get the Australia post mod to work,
The system gives the option to check the postage but then when you enter the details it just sits there.
it's like it is not calling any thing into action, below is the error log stuff.

The lines

$parts = explode("\n", trim($response));

should also really be

$parts = explode("\r\n", trim($response));

otherwise you'll end up with return characters in the array.

So what exactly is fixed here? All this code means nothing to me. Can someone be more specific? I see that many people have had no issues whatsoever with this module. I am wondering why I need to fix anything in the code?
