Hi Dani,
We haven’t had one of these applications for ages either, but we just follow the process in the Act.
That is, refer the application to planning to make sure the land complies with the circumstances set in Sec 585(c), and if so, then refer the application to the VG for determination of any attributable value.
We used to have a number of postponed rates properties under this section, but they’ve all dropped off over the years as the VG determined there was no attributable value.
Cheers
Ian
