Negative gearing is your friend - use it to reduce your tax.

If you have non deductible debt then super MAY not be your best option.
Paying off your non deductible debt should be your No 1 priority.

You really should sit down with someone and go through your goals and expectations/risk aversion tendancies and then develop a plan based around those factors specific to you.

Salary sacraficing super has its place but your age, salary and current position need to be taken into account.
