After picking up a bag full of rubbish on her street and realising the environmental damage, 12-year-old Nikiah Nolte sent a letter to Prime Minister Scott Morrison asking for more Clean Up Australia days.

"At school we were talking about pollution and the damage it has on our oceans," Nikiah said.

"I thought I'd write a simple letter to the Prime Minister as I want to see more people picking up rubbish. There's always heaps of rubbish around."

In her letter, Nikiah explained to Mr Morrison how the coronavirus pandemic could have a positive effect on the environment.

"Mr Morrison, I really believe we should have another Clean Up Australia Day while we are still in isolation," she wrote.

"We could go for a short walk and gather any rubbish we see. We could make sure that the COVID-19 requirements are followed."

Nikiah's aunt Lois Morrow was inspired by the year six student and got to work cleaning up her own neighbourhood.

On a single kilometre stretch on both sides of Wollaston Road, Mrs Morrow collected six garbage bags of rubbish and a bumper bar over two hours on Sunday afternoon.

"What got me really going was my little niece's letter, it pulled on my heart strings," Mrs Morrow said.

"There's always containers thrown out of cars, people have their meals and then just chuck them out.

Mrs Morrow said a number of her friends had also commented on the rubbish they had seen including glass bottles and dog poo wrapped up in plastic bags.

"I've never seen the place like this, there's just rubbish everywhere," she said.

"People have more time on their hands now; next time when you're walking get a little bag and pick up some rubbish."
