The device, which she created for her Design and Technology major for the 2023 HSC, attaches to a drench gun, which is usually used to drench and medicate animals.

The squeezing action counts the sheep that pass through.

The Frensham graduate, who was involved with the school's sheep team, undertook many tests to ensure her product was effective.

The project Sheep counter for drench gun is one of 40 HSC major projects that have been selected as part of the SHAPE showcase in Sydney.

The exhibition highlights excellence for students who studied Design and Technology, Information Technology and Textiles and Design.

The graduate said there were many stages in the SHAPE process in the lead-up to being chosen, and it was an honour to be exhibited with other students.

"It was really cool cause I worked [for] really long on my project and appreciate how long they worked on theirs," she said.

Not only was her major work recognised in the exhibition, she was won a Spruson and Ferguson IP Award.

The intellectual property provider sponsors the award, which recognises students whose projects have the potential to obtain intellectual property protection and have commercial success.

"It was really cool to be awarded that," Miss Arnott said and did not expect the accolade.

Since finishing school, the former student has returned to her family's sheep-producing farm in Coolah in the state's central west, and is working as a station hand.

She will then head to the Northern Territory to work at a cattle station to see the "different ways to work" on a farm.

"I just love that every day is a different day," she said.

Oxley College graduate Hannah Zupp's work The roots of illumination, which incoporates fungi in furniture, is also featured.

All of the major works can be seen at the Walsh Bay Arts Precinct until May 17.

It is free to see.
