Google is bringing its audacious internet-transmitting balloons to Australia.

The company will test-fly 20 balloons in western Queensland in December in partnership with Telstra.

It's the latest step in Project Loon, Google's plan to beam internet to remote parts of the world via helium balloons that circle the globe on stratospheric winds.

The balloons carry antennas that can beam 4G-like signals to homes and phones 20km below.

For the trial, Telstra will supply base stations to communicate with the balloons and access to space on the radio spectrum.

It follows initial trials above Christchurch in New Zealand in June last year. Google said at the time it was drawn to the area's favourable stratospheric conditions.
