They once again put themselves in the picture to clean up their local parks, waterways, beaches, sporting fields, bushland and roadways - the local environment that is important to them and their families.

Since the event started 25 years ago Australians have donated more than 28.75 million hours towards caring for the environment through Clean Up Australia Day, removing an estimated 302,213 tonnes of rubbish from more than 151,919 across the country.

Ian Kiernan AO, Chairman and Founder of Clean Up Australia, speaking from the 2015 Clean Up Day headquarters in Sydney, where the inaugural event was born, is passionate and proud of his fellow Australians.

"Clean Up Australia Day always makes me so proud to be an Australian. We not only put ourselves in the picture, get involved and get our hands dirty, we are also challenging our governments to implement effective waste management and recycling programs. This is a great community event bringing friends, families, neighbours, team-mates and colleagues together like no other activity. We should all be proud of our outstanding success," he said.

"The support for the event continues to grow across Australia as we become more aware of the importance of protecting our local environment. Early figures predict volunteers will have removed around 13,563 tonnes of rubbish, just the beginning of what is shaping up to be a tremendous effort yet again."

Clean Up Australia Day is made possible every year from support from all sectors of the community - government, councils, corporates, local business and most of all volunteers who work tirelessly every year to make the event a success.

"As demonstrated again these volunteers continue to find a staggering number of cigarette butts and recyclables such as glass, plastics and paper continuing to clutter our parks, beaches, waterways and road-sides."

Around 80 per cent of the rubbish removed each year is recyclable.
