The Australian Competition & Consumer Commission on Thursday recommended a mandatory choice screen, offering alternative search engine providers, be displayed on current and new mobile devices that run Google’s Android operating system. The watchdog is also considering extending the change to Apple Inc.’s iPhones and desktop devices.

The ACCC said it may demand that users also be offered a choice of internet browsers.

The plan follows a similar arrangement in Europe, where Google has set up a choice screen on Android devices to let users pick search engines run by smaller rivals. Still, the company’s integration of Google search into Android goes beyond basic text input — it’s part of the voice-activated Google Assistant and several other structural features of the operating system. The provider choice would be just one step toward shaking up the company’s dominance.

Google has a 94 percent share of the search market in Australia, the ACCC said. Further measures from regulators would prolong an assault on its dominance in the country, which this year passed a world-first law to force Facebook Inc. and Alphabet Inc.-owned Google to pay publishers for news.

The ACCC said it plans to start consultations on the proposals. Google is the default search engine on the two most-popular browsers, Google’s Chrome and Apple’s Safari, which are pre-installed on most mobile devices in Australia.

“Google’s existing dominance and its commercial arrangements have significantly increased barriers to entry and prevented new or emerging rival search engines from reaching consumers,” ACCC Chair Rod Sims said.
