After her death, Christie's family vowed to create a positive legacy that would allow other teenagers to do some of the things Christie had wanted to do.
The Christie Marceau Charitable Trust was launched in 2012 and it announced that a scholarship would be awarded enabling a young person to attend an Outward Bound course. The scholarship is funded by donations.
On Christie's birthday, Carmel College student Harriet Clarke, 18, and 17-year-old Junior Kasiano from Mt Roskill Grammar were named as the inaugural winners of the scholarship.
The pair were among five finalists who were interviewed by the trust board, including Mrs Marceau and Christie's sister, Heather.
"It was a really tough decision because all five that we interviewed stood out in their own unique way," said Mrs Marceau. "Me being me, [I] wanted to give it to all of them but Harriet and Junior just had that extra little spark.
When we met her, I instantly knew that Harriet was the type of girl Christie would have given a lot of time to. I just instantly warmed to her as she was such a lovely girl. I guess in a way my decision was based through Christie's eyes.
Mrs Marceau said the decision to award the second scholarship was spontaneous.
"The trust was able to award Junior the scholarship thanks to a very generous donation from a co-sponsor. We are extremely thankful for this as both Harriet and Junior are equally deserving."
She said announcing the winners on Christie's birthday was deliberate.
"It was a way for us to celebrate Christie's life and a milestone that we had been robbed of physically celebrating. It is a gift from Christie and keeps her memory alive and close to us,' Mrs Marceau said.
"These two scholarships are the first of many to come and I know Christie is happy that we are giving back a little for all the love and support she and our family have received."
Harriet could not believe it when she was told she had won.
"I was speechless ... but I was just so thankful for the opportunity. It is a dream come true," she said.
Christie Marceau would have turned 21 last week.
"The opportunity to do the course is amazing, but the opportunity to meet the people that make up the trust was also great. They are so inspiring."
Junior was overwhelmed when he heard the news.
"I was over the moon. It wasn't expected, but I was really happy," he said.
Both teens knew about Christie's death and felt honoured to be part of her legacy.
