What’s the rough population? What’s a serious crime? 50 to 100 a day is 18 to 35000 serious crimes a year. Where are you getting your stats?

Because if it’s not Brisbane, then it’s like one in 10 of the population of gold coast or central coast per year having a serious crime or one in 3 for Townsville or smaller. Seems unlikely to me, but I’m open to seeing your data.
