It makes sense, but with the current economic situation that we are all in, don't forget to to requote your insurances/CTP.
For NSW, it will be https://www.greenslips.nsw.gov.au/. Typically, prices will be within a few dollars, but today as I was about to blindingly renew my CTP, I found that Allianz was $100 cheaper than all the other major offerings.
This goes for everything else, but taking advantage of first policy discounts, I was about to save over 50% on my comprehensive insurance too, going from the renewal cost of $676 to just $316/yr.
CTP should all be roughly the same. The $100 off is for "good driver" discount that some of the providers offer.
QBE does this too but you need to be Australian citizen/drivers license, over 30 and no demerits.
