Fiona and Shrek were walking along the footpath when Fiona stumbled and fell into a hole in a footbridge. The hole had been dug that morning by Andrew and Chris, who worked for the Rocks City Council. Fiona was carrying a set of three china ornaments that had been in their family for generations. At the time Fiona fell, she and Shrek were in deep conversation because they were on their way to have the ornaments valued at an antique show and auction. They were all broken when Fiona fell. 

Required: 

Advise Fiona on her likely success in an action for negligence against the Rocks City Council.
