The medical student is embarking on a four-week placement in general pediatrics at the hospital as part of her degree and said she was keen to get started.

Ms Clark has just completed her fifth year at UNSW's Rural Clinical School in Wagga Wagga and said the placement was "sort of like the choose-your-own-adventure part of our degree".

"I'm really excited. I've heard a lot of good things and there are a number of students who went last year and said they had a good time," Ms Clark said.

The 23-year-old will follow it up with a second placement at John Hunter Hospital in Newcastle.

She will spend a month in the pediatrics rehabilitation ward, helping children to "improve their quality of life and function".

"I really like rehab as a specialty because there's a lot of long-term care," Ms Clark said.

The close proximity to her home town is also a draw card because she hasn't been able to visit much this year.

"I wanted to go somewhere closer to home ... but I'm also sort of sussing it out for internship," she said.

"I'm excited to see specialist services that can be offered, the opportunities that can bring and seeing how much that benefits patients."

Both placements will give Ms Clark a chance to find out whether pediatrics is for her.

"I always think I'm sure [about my specialty], then something happens and I'm not sure any more," she said.

"It's definitely easier to rule things out, then rule things in. At the moment, I really like pediatrics, but it also really excites me to be able to serve a community as someone who can do it all, so being a GP appeals to me."

Ms Clark said she was captivated by the biology of the human body because it "so often functions perfectly and we don't need to think about it".

"From a creation sense, I've always marvelled at the human body but also had the drive to help people," she said.

"Definitely growing up in Gunnedah and seeing [the town] struggle with a lack of doctors at different times, or lack of access to services, means I've always been very keen to serve the community in ways people actually needed.

"I get to help people on a daily basis in a practical way that is beneficial for them."

Ms Clark said she was "relieved" that the "most difficult year of our degree" was over but sixth year has "its own challenges" such as applying for internships and deciding which direction to head in

"I feel like I'm through the hardest part of the degree but there are still a number of things I have to accomplish before I'm fully there," she said.
