[38] In March 2004 Mr Nguyen proposed to Mr Condo that he would build some greenhouses on the Esk property for which a council approval was required. Mr Condo responded "you do whatever you want". Mr Nguyen paid $3,960 to his neighbour to level the property to create a pad for the greenhouses. Mr Nguyen estimates the cost of the steel, some of which he purchased for the steel frame for the greenhouses for which he paid cash and some of which he obtained from friends, at about $30,000. Mr Nguyen was able to produce the receipts for other expenses incurred in the construction of the ten greenhouses. These included the sum of $9,202.60 for shade cloth, plastic materials and the like (exhibit 16), additional steel materials at a cost of $1,651.45 (exhibit 17), transport costs of $396 for materials used in the greenhouses (exhibit 18), $3,553 paid to APack Pty Ltd for mesh and wiring (exhibit 19), $344 paid to the Esk Shire Council for building permit application fees (exhibit 20), sand and concrete for the base of the greenhouses costing $100 (exhibit 21), and another $520 on sand, concrete and pebbles (exhibit 22).
