Trevor is the sole owner and operator of "Honey Bee Nature Appreciation Tours" (HB). He operates walking tours of Bushland surrounding the Bunya Mountains. The bush tracks used are not particularly strenuous. Trevor takes a group of no more than six paying trekkers once per week on a six hour walk during day light hours to engage in bird watching and similar activities. Trevor insists that clients wear sensible shoes and clothing during the walks and that all walks are conducted during daylight. He explains that in the past he conducted night time trips but he cancelled them after several trip and fall injuries to clients. He also supplies water and sandwiches. Trevor is an environmental science graduate of USC. Anna, a café owner, attends one of Trevor's walks. She is dressed in shorts and shirt and a new pair of running shoes. Anna also brings a bottle of wine because it is her birthday. During the midpoint break, produces the wine and offers it to other walkers, who refuse to imbibe. Anna drinks half of the bottle and feels a bit tipsy. Trevor left the walkers alone during the break to scout a new location. However, Trevor is lost in his work and takes much longer than he thought. The team returned after sunset when the forest was dark. On the return walk, Anna's feet become sore, so she changes out of her runners and into her high heel shoes that she brought with her as a backup. At this time, Trevor was observing the rare Marbled Frogmouth perched in a tree.Later near to the end of the walk, Anna's heal catches on a tree root and she stumbles down a hill side injuring her knee. Anna is transported to hospital. While in hospital Trevor visits her and expresses his regret that the incident occurred. While Anna fully recovered in a month, she closed her café and decides to sue Trevor in Negligence and claim 12 months in lost income and punitive damages to punish him.Advise Anna as to her case for Negligence against Trevor. Do not discuss any defences apart from Contributory Negligence.
