An Australian teacher who won $20,000 on a TV game show will buy new shoes for the students at her school.

Bri Dredge, 32, who was on Millionaire Hot Seat on Thursday night, has decided to use her winnings to help pupils at Yuille Park Community College in Ballarat.

"I walked into school and every student in the whole school has given me a hug and said thank you," Dredge told AAP on Friday.

"The look on their faces was worth all the money that I won."


All 200 students will receive a pair of sturdy leather shoes to get them through Ballarat's long, cold winter.

Dredge says her time of the quiz show was "scary" but hopes it inspires the students to get out of their comfort zone and challenge themselves.
