Many commentators are comparing the current potential for a couple to place over $1 million into super by 30 June 2017 with the Peter Costello top up of a decade ago. On 5 September 2006, the then-Treasurer said, "People will be able to make up to $1 million of post-tax contributions between 10 May 2006 and 30 June 2007." The inflow to super was unprecedented. In 2007, SMSFs alone received contributions of $70 billion compared with only $20 billion in 2006.
