Amount of cover is a really personal thing so I probably can't help you there. DH and I both have enough life insurance to pay off the mortgage, take a year off work and enough left over to invest and provide enough income for childcare so we could return to working.

When we looked into it we found insurance through super much more expensive and less flexible than elsewhere but some people prefer it as its paid with pre tax dollars. Also look into whether you want level or stepped premiums. Level are more expensive now but will work out cheaper if you continue the policy around 10years plus.

Do you have income protection insurance? If your the sole earner for your family that's the first thing I'd be getting. And it's tax deductible.
