The website, launched by five leading charities including the Salvation Army and St Vincent de Paul, features information about what can be donated.
The key feature of the website is the ability to enter a postcode which brings up all nearby collection points.
Environment Minister Albert Jacob said the website would help to reduce illegal dumping at drop-off stations, which costs charities hundreds of thousands of dollars each year to clean up.
“The practical information on the website will make donating unwanted goods a lot easier,” he said.
“The website also has useful advice on how people can recycle goods that aren’t fit for donation.
“Better disposal of goods will result in less waste going to landfill and support the valuable role these charities play in the community.”
The website was developed following a $100,000 grant from the State Government through the Waste Authority.
Vinnies spokeswoman Joanne Hill said it was a great example of how charities and government can work together to help the community.
Other charities involved include Anglicare WA, Good Samaritan Industries and the Spine and Limb Foundation.
