Mount Clear sisters Izzy, 6, and Claire, 4, are making new friends in their neighbourhood, while improving their reading and writing skills and following social distancing rules during the coronavirus pandemic.
Both have started writing daily to pen pals and walking around their suburb to deliver the hand-written letters.
Izzy is now writing to 14 new friends, after her mum Chris Hutchinson put a call out for pen pals on the Sailors Gully Neighbourhood Facebook page.

Ms Hutchinson said she came up with the idea as a creative approach to maintain reading and writing and create a new form of in-home entertainment during the school holidays.
"We usually write around two letters a day at the moment. We go for a walk every day and post the letters, which is our exercise. It gets a few different elements in one from the school day," she said.
"Izzy gets very excited checking the mailbox all the time."
Ms Hutchinson said her youngest daughter Claire was also benefiting from the activity.
"She was getting a bit jealous that Izzy was getting all this mail, so she has decided to start writing some letters as well," she said.
"She is only in kinder, but she is practicing her writing. Whenever we go to post the letters she is the one who counts all the numbers and finds the letterbox we need to put them in, so for her it is a bit of a learning experience as well."
Ms Hutchinson said letter writing was an activity children in any neighbourhood could do.
She said her daughters were looking forward to meeting their new friends once the social distancing restrictions were lifted.
"Already families see us walking in the neighbourhood and know we are off to post our letters," she said.
"We will hopefully get to meet a few of these people, as many of them live around the corner and are similar ages.
"They are finding out about each other, what they like and dislike and have a few things in common too."
