Better protecting oceans and marine life is the focus of a $100 million package announced by the federal government as it faces pressure from the US to do more on climate change.
The funding will go towards ocean management and methods to draw carbon out of the atmosphere involving seagrass and mangroves.
Prime Minister Scott Morrison said the climate and the oceans were inextricably linked.
"This investment will boost the seagrass and mangroves that will help cut emissions and it'll mean cleaner beaches, lower fisheries bycatch, more fish stocks, better protection for turtles and seabirds, and help for coastal and Indigenous communities reliant on the ocean for their livelihoods."
Environment Minister Sussan Ley said the funding would help tourism, research and fisheries.
The money will also go towards supporting Indigenous protected areas.
The government has already announced bans on waste exports, which started in January with glass.
Bans on plastic, paper and tyres will be staggered, beginning from July through to July 2024.
Australia's environment ministers are also planning to phase out a range of "problematic and unnecessary" plastic products over the next four years.
Lightweight plastic bags, straws, utensils and stirrers are among the list of products the ministers want to eliminate by 2025.
