It's the small gesture that has been making a big difference in the lives of isolated Blue Mountains residents during lockdown.
A group of teenagers and young people has been checking on the well-being of vulnerable members of our community by surprising them with phone calls.
The cohort of COVID callers, aged between 17 and 25, came together after Federal Macquarie MP Susan Templeman sought their advice and input on a range of local issues.
"The group volunteered to call older people to ask if they have the essentials, if they need anything, and sometimes just to chat about the garden," said Ms Templeman.
"I don't think any of them had done something like this before, and it can be a bit daunting picking up the phone and calling someone you don't know.
"But in just two weeks they made more than 300 calls, with some conversations lasting about 15 minutes.
"Some people are busy or don't particularly want to chat, and that's fine, but those that do have commented how nice it was to receive a call - especially from these dedicated young people."
Blue Mountains group member Chris Timbs, 22, said the calls were a win-win for both the young people and older residents they spoke to.
"I think it's important to be reaching out to the community at the moment because we are arguably more isolated from each other than ever before - it's not as if you can stop and chat to a stranger at a book shop or a cafe," said the Sun Valley resident.
"I've found that for some of the elderly community members we've called, it has been their only contact for the day, or a refreshing change of pace to chat with us after days full of gloomy news headlines - to be part of that is a great feeling.
"I'd say that it's win-win, you get to make someone's day, they can chat to you about what's on their mind and how they're feeling, and I've come away from every call learning something new from people who have so much life experience and wisdom.
"Why not pick up the phone and make a genuine connection in such a distanced and lonely time?" he said.
Ms Templeman said the group's activities came as some refreshing good news during such a challenging time.
"Lockdown has been extremely challenging for everyone in the Hawkesbury, Blue Mountains, and of course Greater Sydney area, and for many the social isolation can affect their mental and physical health," she said.
"These young people, and I, know we need to emerge from this lockdown with our community intact - regardless of your age, gender or postcode.
"I'm really proud of the outreach they are doing, and I'd like to congratulate each and every one of them for their personal commitment to our community... We are all in this together, we're on your side, and we don't want to see anyone left behind."
