We're saving by putting extra money into our home loan, which we can redraw if we ever need it in the future. It's conceptually the same as a savings account paying 6.82% p/a, but the effective return is higher because it's a reduction in interest charged, rather than interest income (which would be taxed).
So far we've got about 4% of the total value of our home loan sitting in the account as excess funds. Not bad considering our loan was fully drawn only 5 months ago.
