For what it’s worth, my two cents’ worth re Unanderra station.
Isn’t it ironic we have three freshly painted disability parking spots, a platform specifically made for disability access – and a bridge suited to only the fit and able to get to that platform. Very useful that.
I have lived in the area from around 1958 when we did have a perfectly accessible station. All we had to do was cross the road.
Then someone had a bright idea. Build a bridge and block the road. That really improved access.
Simple. Get rid of the bridge. No problems with lifts and the issues they bring.
Cheap and cheerful.
