Maddison was one of 500 students from across the country who applied for the scholarship program that provides financial support for an undergraduate degree at the Australian National University (ANU) as well as the opportunity to make a difference in the world.

Maddison said it didn't feel real when she received a phone call last week letting her know her application had been successful.

"It was very exciting. I called my parents straight away," Maddison said.

"It's still sinking in. I'm not quite sure I fully understand the amazing opportunity I've been given."

Maddison gained the scholarship after making it through a three round application process that involved two online stages and an interview weekend at the University.

That weekend involved individual and group interviews with a selection panel that included Graham and Louise Tuckwell, the driving forces behind the scholarship, a Nobel Laureate, a Rhodes Scholar and a former Chief of the Defence Force.

Maddison also took part in group activities where the panel assessed each applicant.

She said she was unsure at first what she could bring to the table, but soon relaxed when she chatted to fellow applicants and reflected on the opportunities Blayney High School has offered her, particularly to enhance her leadership.

"It was really good to compare experiences," she said, adding that the process was not competitive as some might think.

The "no ordinary scholarship", as it is billed, is only awarded to students who demonstrate a broad range of attributes and display academic potential, significant achievements, a desire to give back and embody the Tuckwell vision.

"This program is designed to be the most prestigious undergraduate scholarship in Australia, for a group of students and alumni that will build over time and who will inspire and support each other to achieve great things. That's why we're doing this at a single university, as it is important that these Scholars interact with and feed off each other," Mr Tuckwell said.

The scholarship will also allow Maddison the chance to connect with like-minded individuals across the ANU campus and play an active role in coordinating social events and seminars.

Being awarded the scholarship is a dream come true for Maddison.

She has had her sights set on attending ANU since she was in year 9 and has chosen to persue a five-year double degree in Law and International Relations at ANU.

"It's a lot of hard work, but it's where my interests are."

The scholarship is conditional on Maddison achieving an ATAR of 95 or above.

But knowing her university costs, including on-campus residential costs, books and general living expenses will be taken care of, has eased the stress burden, albeit slightly.

"It has created a new level of stress; a different kind of stress," she said.

"It has given me the motivation to study."

ANU Vice-Chancellor Ian Young welcomed the new scholarship recipients to the university community.

"We are delighted with the standard of applicants this year," Professor Young said.

"I'm excited to be welcoming all the Tuckwell scholarship recipients onto campus and looking forward to the contribution they will make to ANU."
