Senator BOSWELL (Queensland) (14:29): Mr President, I ask a supplementary question. Seafish Tasmania has worked with Commonwealth officials for seven years. It has met all of AFMA's regulations and now finds the rules have suddenly changed. Is the government prepared to offer compensation to Seafish Tasmania and the small family fishing companies that intended to lease their quotas to Seafish Tasmania and who now face owning an asset that is near worthless. Has the government calculated the cost of compensation?
