Meanwhile, the Australian Marine Conservation Society (AMCS) has called for the state government's announcement to ban single-use plastics to be accelerated.

The Society welcomed the ban saying WA's dolphins, whales and seabirds would soon have safer seas.

"In particular, we know that soft plastics like shopping bags and produce bags are some of the most lethal to ocean wildlife, entangling and drowning small creatures or causing life- threatening blockages when eaten," plastics spokesperson Shane Cucow said.

But Mr Cucow said the timeline of year 2023 needed to be accelerated to reflect the urgency of the crisis.

"Every day we wait thousands of ocean animals die, killed by the plastic trash filling up our oceans globally," he said.

"With plastic waste increasing rapidly, it has never been more urgent to act. We urge the WA Government to start banning stage one plastics by the end of 2021."

The state government's Plan for Plastics will be rolled out in two stages.

In the first stage (2020 to 2023), the state will ban plastic plates, cutlery, stirrers, straws, thick plastic bags, polystyrene food containers, and helium balloon releases.

In the second stage (2024-2026), the state will ban single-use plastic barrier/produce bags, microbeads, polystyrene packaging, cotton buds with plastic shafts and oxo-degradable plastics.

All together, the full list of banned items is the most ambitious in the country, including items such as heavyweight plastic bags, microbeads, and produce bags that have not yet been included in South Australia or Queensland's bans.

WA will join SA, Queensland and the ACT as the only jurisdictions banning single-use plastics beyond plastic bags.

SA passed laws to ban single-use plastics in September, commencing early 2021.

Queensland and the ACT have draft laws currently being considered in their parliaments.

WA also introduced its Containers for Change scheme in October which allows Western Australians to claim a 10 cent refund.
