Use TID0318 for 10% off Travel Insurance (however this discount doesn't seem to apply to the Excess Reduction amount that adds on to the premium).
Don't forget to book through Cashrewards to get 7.00% cashback (the 7% rate is a limited time promo and will revert back to 4.20%).
NOTE: This coupon (TID0318) is not listed on the Cashrewards site so the cashback may be declined. YMMV.
I found www.insureandgo.com.au much cheaper and you get a discount via the Entertainment Book too…
They were also the ones that paid the most out for rental car excess…
