Millions of Australians are set to benefit from a new free waste disposal service targeting problematic household substances.

The initiative aims to help residents safely get rid of hard-to-dispose items that can harm the environment and public health.

Local councils say the program will reduce illegal dumping and ease pressure on landfill sites already nearing capacity.

Households will be able to access designated collection points or special pick-up services for certain waste materials.

Authorities believe the move will also improve recycling rates and encourage responsible waste management across communities.

Officials are calling it a major step toward cleaner suburbs and a more sustainable future.
