But little to her knowledge, the ones she grew up with weren't her only siblings.
Ms Clark was 25 when she went searching for her dad, Alan.
"When I went to try and find my dad, there was no such thing as Facebook then," the now 43-year-old said.
"So I wrote the same letter to 31 Alan Clarks in the country and later found him in South Australia."
After she found him, Mr Clark was not forthcoming about her half-sisters. It wasn't until an aunt told her two years later that she learnt about them.
"My Aunty Gloria, before she passed said I had two sisters but at the time, the family said she might have been confused, but I was persistent with my dad and it came out."
Their names were Tracy and Jasmine, and they lived and grew up in Canberra.
Ms Clark, who moved to Canberra from Melbourne more than two years ago, sat on this information for almost six years, nervous about what would happen if she reached out.
"You don't know whether there's going to be rejection, you don't know whether there's going to be a happy ending."
At 7.49pm on Monday, June 11, 2018 Ms Clark took to social media to track them down.
"So many times I thought I'd put something out there and then I'd delete, delete, delete and then I was just sitting on the couch scrolling on the Canberra Notice Board page and I just thought - you know what, yeah I'm going to do this," she said.
"Hi all this might be a long shot but I'll give it a go," the post read, before it described her search.
Within half-an-hour, the sisters reached out to her.
Ms Clark's half-sisters Jasmine Johnson and Tracy Kruska, who were not part of the group, were alerted to the post within minutes.
"It just amazed me how quickly things have come together," Ms Clark said.
A group member, who went to primary school with the sisters, had messaged them about Ms Clark's post.
The story has captivated Facebook users who watched the uniting unfold.
"It's just crazy to see the response of people from the group," Ms Clark said.
"They're watching this play out as well and so many people were watching it and saying 'this is giving me goosebumps and everything' and I'm reading and going - 'giving you goosebumps? It's freaking me out'."
Ms Johnson, 35, messaged Ms Clark and the pair met the following day.
"I was fine at work because I had something on my mind, but when I got home and it was a couple of hours before we organised to meet, I was pacing back and forth," Ms Clark said.
"I’m just so, so happy, my nerves left the minute I saw Jasmine and we chatted for hours and no one could take my smile away."
The sisters spent more than four hours talking non-stop. They plan to meet again, along with Ms Kruska, who is now based in Queensland.
Ms Clark and Ms Johnson discovered they lived in the same neighbourhood, actually just four kilometres from each other.
"I have no doubt that we would have been in the same place in Canberra at some point in the last two years," Ms Johnson said.
"We definitely would have crossed paths on the streets but we wouldn't have known."
