In this paper we endeavour to isolate the top ten innovations and developments that have occurred in policing in the last thirty years. We consider that each of them brought about a new mindset, pattern or trend into contemporary police practice. We have focused our attention on the last thirty years because it is during this time that we have both maintained a keen academic interest in the field. While we have focused our attention on the way in which each has affected Australian policing, we are cognisant of the fact that many of them had their roots in other settings long before Australian policy-makers adopted or adapted them.
