The ex-St Mary's College student has raised almost $700 since she launched the campaign on social media last week.

"The fires are absolutely devastating. So many people, as well as so much of our wildlife, have been negatively affected. It's up to the people to do everything that they can and I believe that every small contribution can make a big difference," Ms Taylor said.

"I have also seen many other small businesses do their part to help in some way so that was a huge inspiration for me.

The 18-year-old started her small business, Violette Charms, about 18 months ago and is "glad that I can use my platform to make a positive change".

"I've always had an interest in using my hands and making things. I think I started making little clay figures when I was around 10," she said.

"I honestly forgot about it for a while until the last couple of years when I realised that I could use this passion to make a profit and also use my platform for good."

Ms Taylor is heading off to university next month, so the koala line is only available until February 15.
