IME, it took about 7-10 days for IB segments to credit to my QF account.
I have previously used the Feedback page on the Qantas website to make claims for missing points:
http://qantas.custhelp.com/cgi-bin/q...nduser/ask.php
Select Frequent Flyer > Missing points from the dropdown menu.
Qantas have accepted JPEG's (from a digital camera) of my paper tickets and boarding passes previously, when I have made claims whilst still travelling.
I may have just gotten lucky, however.
