EDIT, use the REW20K code as CARX03 has expired
Third time I'm using this code (CARX03), always marked expired but comes back active each year somehow.
Works for 3rd party and 3rd party, fire, and theft too (not just comprehensive).
More expensive than Bingle ($100 gift card brings it closer to par with higher excess) but cheaper than all the other insurers I tried.
or credits to Maichu https://www.ozbargain.com.au/comment/12336502/redir for this code REW20K which gave me a better price and 20,000 rewards points (worth $100) instead of $100 egift card.
