So I can confirm that you do receive points for making payments to the ATO on the Woolworths Credit Card.
So I took a balance transfer option from Citibank, put an extra $15k onto the wow CC, made a bulk payment to ATO before the indexation was applied and now have my HECS debt on a 12 month interest free loan and getting the extra 5%.
With my tax returning coming up, since there was a HECS/HELP withholding, I'll get this all back (Around $8k just in HECS/HELP withholding) and some other deductions which would amount to a decent size tax return. So instead of paying my HECS through the compulsory payments, managed to pay it off with a credit card earning just over 13k points and shaved 5% of the total balance owing while also missing out on the 2.6% indexation that was to happen on the 1st June. With the 12 month balance transfer from citibank, should only have around $2000 to pay off over 12 months.
