The Major question is whether you remain a resident for tax purposes, and there is a checklist the ATO utilize.
If your work, income, primary residence and Family are all here, you are non-resident.
That means you are not liable to Australian tax on overseas earnings, but for any Australian earnings (rent, dividends etc.) you are treated as a foreigner.
If you are Commuting, keeping a residence and with Family primarily in Aus, your status might be questionable.
Yes, your SMSF is an issue- different laws apply to Non-residents and you will probably have to roll it over to a normal Fund.
I'm no expert, so I guess the additional advice is "Consult an expert" but I hope that helps!
