City Plaza used to be home to some small retail outlets, a library and the BCC customer service centre. It was squeezed in between city hall and the council administration building.
It is now all gone and has been replaced a 30 storey high rise office block called 275 George.
Google Earth still shows an aerial view City Plaza while street view shows the construction hoardings around the new building.
However two small bits of concrete from City Plaza remain. They are located in a quiet area where City Plaza, City Hall and the admin building once met and are the reason for the cache.
Although the general area is now covered with cameras this little spot seems to have been ignored. The cache is not hidden in the gardens, the sculpture or in the white rocks underfoot.
Because of the flaky GPS signal, the hints below are intended to make your search short and sweet.
