The respondent (Banks and Sons) leased the appellant's (Koala Park's) farm from 1985 under two lease agreements. The first lease (old lease) terminated in 1981, and a second lease (new lease) commenced on 1 March 1991 for a term ending 28 February 2001 with an option to renew. In September 1991, David Dyer purchased 95% of the shares in Banks and Sons for $1.6 million. Prior to Dyer's acquisition, Banks and Sons had made certain improvements to the farm, including a butchery building and bottlestore building. In 1994, the parties had a disagreement resulting in Koala Park successfully suing for eviction. The new lease contained clause 8, which provided that the lessor would resolve in writing within twelve months the amount and procedure for compensation for existing and future buildings. Clause 10.1(e) provided that alterations or additions required prior written consent and would become the lessor's property without compensation unless otherwise agreed in writing. On 4 June 1991, Koala Park's managing director (Shelton) wrote a letter stating no compensation was appropriate for existing buildings. Banks and Sons claimed $1.7 million compensation for improvements. Koala Park counterclaimed $184,000 for items allegedly unlawfully removed from the farm.
