Aussies will soon be sipping through paper straws at McDonald’s after the company announced it would phase out plastic straws over the next two years.

Environmentalists say the move is a step in the right direction.

A trial of paper straws will start in August in two outlets and will roll out to all 970 restaurants nationwide by 2020.

The move comes as supermarket giants Woolworths and Coles get rid of free plastic bags.

McDonald’s says the trial is part of a larger, long-term global effort to identify viable, sustainable alternatives to its single-use plastic straws.
