If you want to make a difference for your grandchildren, get them a TFN at birth, and if you are self employed, pay the grandchildren a small figure ($100) per year for doing SOMETHING and also up a low fee industry super account in their name. Contribute $1,000 to the superfund as a personal contribution and lodge a tax return for the grandchild. PRESTO- they will receive $500 super co contribution. We have 10 grandchildren and they are all "on the plane" with the this and they will all benefit later in life. My son who is now aged 28 started this aged about 13 and salary sacrifices a little also and has just over $200K in super.
