Clean Up Local is a Facebook group started in April by 6-year-old Harper Ling after she visited a rubbish-ridden beach and decided it was time for change, according to father Marcus Ling.

"Harp noticed some trash on the beach and she wasn't happy about that," Mr Ling said.

"Over the last couple of years she's seen more rubbish and litter around and decided she was sick of seeing that.

"So we sat down as a family and thought 'how can we try and fix this problem?', Clean Up Local is what we came up with."

The group visits an area of Launceston one Sunday every month to pick up as much litter as they can find. The area chosen for August's clean up was the playground on Lilydale Road, Rocherlea, Mr Ling said he anticipated heaps of rubbish would be collected from the day.

"The last Clean Up Local day on the East Tamar had 15 full bags of rubbish collected, we hope to match that, if not more," he said.

In the months since it's founding, Clean Up Local has grown with every 'share' on social media, according to Mr Ling.

"We [Clean Up Local] thought we'd put word out on Facebook about it and this is what it's grown to so far ... Our page is growing by the day," he said.

"To see her [Harper's] classmates as well as the kid's cousins jump in on the day... it just makes you proud as an adult and as a parent to see that next generation come through and really give a stuff about the environment."

Mr Ling added other Launceston-based community groups, including Plastic Free Launceston, have come out in support of the group and have helped raise awareness through their channels.

"People are returning, and we're getting new people as well which is great ... Even Harper's little brother who's just turned four is really happy to jump in on the clean up days," he said.

While the message of Clean Up Local is a serious one, children's smiles were aplenty as they cleaned up.

"They [kids] have a bit of fun on the day and they pick up the rubbish, chuck it in the bag and they can't wait until the next one," he said.
