Fifteen-year-old Brittany Goss was hit crossing the West Tamar Highway at 6.10pm on Friday and later died in Launceston General Hospital.

Exeter High School principal Maree Pinnington said Brittany was a "delightful" student who would be greatly missed among the small school of 375 pupils.

"The school community is shocked and devastated by the news," she said yesterday.

"Brittany is going to be sorely missed."

Brittany was a student in year 10, which has 90 pupils.

"Being a reasonably small school it has a really close-knit family feel about it with the staff and the students, so it's going to rock them big time," Ms Pinnington said.

"I have been talking to my learning support staff to make sure we have support in place for staff and students when they return next term."

Tribute messages continued to be posted yesterday on social media in honour of Brittany.

"We'll never forget her because she's a part of our hearts now," a Facebook tribute said.

West Tamar Mayor Barry Easther said words were not sufficient to capture the sense of loss in the community.

"The whole community has the Goss family in their thoughts and prayers," he said.

"It's a tragic loss."
