IMHO you are always better off transferring max amount into pension phase (at the start of the FY) to maximise the potential tax benefits...you should keep an eye on your pension account to ensure it does not exceed the cap anytime during the FY.
if your not retired then you will have a TRAP and taxed @15% for earnings made (10% for concession CGT)..you will need to meet your annual pension withdrawal minimum (the withdrawal will reduce your pension account balance)..the withdrawal will be tax free even you are under 60..
its not compulsory for you to withdraw lump sums from your accumulation account, you may only do so if you satisfy the condition of release (ie retired and over preservation age/turn 65).
if your retired then you will have a SABP which grants you tax-exemption for all earnings made from your pension account..still have min pension withdrawal obligation but no maximum in this case. earnings made from accumulation account are still taxed at normal rate (15%)
based on your personal tax rate you might decide how much to withdrawal from your Super and re-contribute to maximise tax benefits.
