The development of CORO can be traced back to the early 1990’s when trust account inspectors across Australia met annually to discuss various regulatory issues.

In 1992 the first National Conference of Regulatory Officers (CORO) was held in Victoria. The 1992 CORO Conference was a great success. Regulators attending the 1992 Conference expressed a willingness to share information and material and agreed to work together to build on current experience. Since then CORO has met on annual basis.
