The ancillary development exception in cl 37A(1) of Sch 3 to the EPA Regulation 2000 (NSW) involves a dual test: the putative designated development must be (a) ancillary to other development in the sense of being subservient to and serving the purposes of the other development, and (b) not proposed to be carried out independently of that other development. The test under paragraph (b) is objective, assessed by reference to the development application and accompanying documents, not the subjective intentions of the applicant. The characterisation of development as ancillary or independent is a question of fact and degree assessed from a town planning perspective, and substantial works may fail the ancillary test even where undertaken solely to enable the other development.
