Big Bank Ltd operates nationally with more than 50 branches, a 10-storey head office and numerous call centres. It is registered for GST purposes. Big Bank has for many years provided loans and deposit facilities to customers in Australia. Last year it launched a new product, Big Bank home and contents insurance policies. It was a significant step for Big Bank and required it to change some of its computerised accounting systems due to the fact that GST needed to be charged on the new product.

Big Bank budgeted to spend $1,650,000 (including GST) on advertising campaigns last year. Of that sum, $550,000 was allocated to a television advertising campaign specifically promoting Big Bank home and contents insurance policies. The other $1,100,000 was allocated to a general advertising campaign, including television, radio and print media advertisements promoting Big Bank to the public as the bank that is "Here for You".

When Big Bank Ltd launched Big Bank home and contents insurance policies, it forecast that its home and contents insurance business would constitute 2% of its entire enterprise. Big Bank has been proved correct in its forecasts. The other 98% of its enterprise is made up of its traditional loans and deposit facilities businesses.

Last month, the advertising consultants issued their tax invoice for $1,650,000.
