Google has threatened to pull its search engine from Australia on Friday over a proposed media code that would require the tech firm to pay for news content, dpa said. Mel Silva, managing director for Google's Australian operations, told a Senate enquiry the code was unworkable and the company was unable to calculate the financial risk, news agency AAP reported. Leaving the Australian market is the "only rational rational choice if this law were to pass," she said. The news media bargaining code bill was introduced into Australia's parliament in December. If passed, it will force tech companies to pay news outlets for their content or face fines of up to 10 million Australian dollars (7.7 million US dollars), according to AAP. The code would initially apply to Facebook NewsFeed and Google Search. Also on Friday, Google published a video and letter addressing Australian users in a campaign against the news code. Silva compared paying news outlets for displaying links to their content to recommending coffee shops to a friend and then being billed by the coffee shops for mentioning them. "When you put a price on linking to certain information, you break the way that search engines work and you no longer have a free and open web," Silva said. The company wants to pay publishers through its Google News Showcase programme rather than for links. Nearly 200 publications have signed deals with the programme, Google said.
