red,
go and talk to you financial planner about how much you are able to salary sacrifice into superannuation before the 30 june.
Pay 15% contribution tax into super, however would be less than the marginal tax bracket you will find yourself in. just need to hold some of the gain back to substuitute what you are contributing into super. If you are self employed even easier.
Probably look for a capital guaranteed (listed) product offered by the likes of macquarie and UBS - depends on you investment horizon and how long you think it will take the sharemarket to bounce back - could be a great time to do it.
