Domestic freight by location

I’m setting up my Wix store and shipping options, but I’m stumped on how to calculate freight by location. I’ve selected Australia and all the states in the rules menu. I’ve set some test values in the weight categories. But how to I calculate by shipping destination? Example: Melbourne is 700km from my location and Brisbane is 2500km, obviously Brisbane will have a higher freight cost. But I can’t figure out how to account for this. I must be missing something obvious…
