You can use Google Earth to really explore the OLS in all its (fairly accurate) 3D glory. Check out pictures below for established infringements. The gateway bridges also make for a good indication of the location of the OLS around the airport. Brisbane residents could even calculate the maximum height of their renovations.
And a long time before this, I also drew an exaggerated vertical scale version of a code 3 non-instrument OLS over a remote aerodrome in Western Australia.
