For some reason NRMA are like $100 cheaper than all the others for my CTP.
Comprehensive wise, I am looking at about $900 for $37k agreed value and with a $2000 excess. Rego is due in the next week or so, tis that time of year!
I might tweak the agreed value and excess a bit more tho, see how their silly formulas work out. All I do know is using the NRMA calculator you have up to $1000 worth of leeway in the agreed value that results in the same premium, so make sure you max that out once you find a premium you are happy with!
