Tanya is a drilling engineer who lives and works in Perth CBD. She also owns a hobby farm 4 hundred kilometres north of the city in Geraldton, which she visits on weekends. Tanya has 20 head of cattle on this property, all branded "T". Next door to Tanya's farm lives Wesley, a full time farmer. Wesley keeps an eye on Tanya's farm when she is away. One afternoon, a freak bushfire sweeps through the local area. Tanya's fence gets destroyed and her distressed cattle wander freely onto the road. Wesley tries to contact Tanya, but she failed to notify him that she had to take a sudden work trip to the Middle East. Wesley rounds up the sheep and gets her fence fixed. He provides Tanya the bill. In this scenario, what is Tanya's rights under agency law? Is she obliged to pay back Wesley? What is the relevant law in this scenario? Apply the IRAC method.
