From January 5 to January 10, our broadband usage processing was not working correctly. During this period, the online Usage Meter did not display any of your broadband usage and no usage email notifications were sent. We have now fixed this problem.
When you log into the online Usage Meter, usage between January 5 and January 9 will show as being used on January 10. This usage will count towards your usage allocation on your next TelstraClear bill as usual.
We apologise for any inconvenience this may have caused you. If you have any questions please contact our Customer Care team on 0508 888 800.

So the message seems to be "we messed up, you pay for it". Fortunately for me I keep an eye on my broadband usage and use some common sense so it won't affect me at all, but i'm sure some people will be getting bills they don't really deserve this month.
