It comes down to what industry you are in (high or low risk), the cover amount, and the options on that cover. You also have to consider if you're in it for the cover or in it for the points. Being in it for the cover will get you the points, but not at a good rate. Being in it for the points will mean you can't meaningfully claim, but I would imagine most people in it for points will cancel fairly quickly, like Staples, ANZ Insurance, Regus, Storage King, Caltex Starcard, etc... there have been many such offers.
My industry is IT and I assume that's low risk for Life insurance as well as TPD. Both covers were set to $100,000 with accident cover, but no illness or (adventure) sports cover. I didn't choose the other two covers as they both were significantly higher, much as income insurance would be nice – I don't plan to claim.
My premium comes to $7.56/month.
