In 1935, newly appointed Sydney Police Commissioner MacKay summoned the feuding Devine and Leigh to his office. While he would not vigorously enforce anti-bootleg and anti-prostitution laws, he announced that the new police powers granted to his constabulary would be used against both women and their criminal enterprises unless there was immediate mitigation of gang violence and cocaine distribution. They did so, which left the New South Wales State Police able to concentrate their attention on the illicit cocaine trade in 1938/39. Following intensive policing of overseas supply routes, the cocaine trade finally began to ebb.
