For future reference:

I am rechecking all my changesets that list Council imagery as a source for copyright reasons. 

I do not believe any of the changes in this changeset are directly atrributable to the council imagery.

However, some of the objects are not visible in the DCS NSW Imagery either, so I can't definitely attribute them to a source. 

To stay on the safe side, I have attempted to partially revert the change (first time doing this, let's see how it goes). I chose to keep the trees, swingset, footpath adjustments, and changes to outline of play area as these are all confirmed in the DCS NSW Imagery.
