Hello Emma
I think Paula at Grafton (Clarence) could provide info on an Ipad draw from a few years ago.
Tweed currently have a cash prize for properties paid in full by 31/08/2020 and a cash prize for signing up for electronic notices. Donna Boresch 07) 5586 6103 or dboresch@tweed.nsw.gov.au would be a good contact if you need more info on how this was organised.
Kind Regards
Lee
