Someone has just sent me an SMS

A few minutes passed noon today, I received an SMS message from some number I did not recognise.

Reminder: Your tax return is due 31 Oct. You can use e-tax at Please ignore if recently lodged. Australia Taxation Office.

Thanks for the reminder from our considering government, not. Is it the first time ATO used SMS to remind the procrastinators? Dreadful time of the year again and it is going to be a bit more complicated this time because I've got an ABN this year. Hmm...
