one risk is the loss of transition to retirement pensions(tris)
if you don't know when the retrenchment will take place and you have significant superannuation entitlements already, consider having a tris put in place NOW
also - have your tax accountant weigh up options re having an etp paid now as well
another risk is the abolition of instalment warrants - if you are looking at buying investment property you may want to have a contract in place (warrant must be in place before the contract) before the budget
