Whats with the constant 31 km locality

Why are the majority of most of my search matches or potential people of interest always 31 freeking kilometers away ...like seriously ? They all live in the same suburb???? Even tho my search parameters are way more than this magical 31km radius ..? That 7 out of 10 are always depicted as being .... ? even if i change my location by 31 km they don't seem to differentiate?? ...

I dis a seach the other day.

I changed ANY in the location filter to NSW then clicked town/city and made my selection. It did the same as you.

I then closed my browser and started again. Still failed.  In the third attempt I left ANY alone and just changed town/city and blo me joe it worked granted the were a fair distance but the suburb I selected had the profiles listed with a 10k radius.. not sure if this helps but give it a whirl anyways
