I had a look at this to contextualise to here - the New South Wales police have a 3.9 billion AUD budget for the entire state of NSW, about 2.7 billion US dollars. That is a police force that covers nearly all aspects of policing, ie there are no equivalents to county sheriffs, to state highway patrols or state rangers, to specific college police agencies, etc. NSW Police is it, except for federal customs functions.
That is 2.7b USD for all the policing functions covering about 7.5 million people and an area twice the size of Texas. Austin is a city of 700k people, and its budget is spending about twice per capita on police as New South Wales' police even as the Austin Police have a smaller span of functions given the existence of the state highway patrol, rangers, county sherrifs and college/university police.
