The annual competition highlights the teacher voted the most popular teacher in the Illawarra.

The prize for Mrs Davis, her job-share colleague Mrs Hurley and the 29 members of their class was new iPad minis, courtesy of Domayne Warrawong. The Illawarra Credit Union also donated a $30 Wildlife saver account to each of the students from the winning class.

Mrs Davis said she knew she was in the running for the prize and as of Wednesday night was in second place.

"In the 12 hours between Wednesday night and finish of voting I received an amazing 24,000 votes," Mrs Davis said.

"The radio station rang our principal Mr Grosse and told him I had won, but to keep it on the 'down low', so he told me that the voting was close but not to be disappointed if I didn't win.

"The children were very excited on Thursday morning and some parents also arrived and the kids were looking out for someone in Wave FM gear or a Wave FM car, but instead two men in plain clothing and in an unmarked car turned up looking just like parents.

"Everyone was so excited I was worried they would be disappointed if we didn't win.

"I really don't think the children will have an experience like this in their school lives - it was extraordinary."

Mrs Davis received a staggering 44,000 votes, winning the competition by 9000 votes.

"It's certainly a report card I'm happy to receive," she added.

Mrs Davis, her 5L class and Mrs Hurley each received their prizes on Friday morning in an assembly conducted with radio hosts, Travis and Emma, from the Wave FM.

"I would like to thank the parents of 5L, the community, my friends and family that supported me and my wonderful class throughout the competition."

Many of the nominated teachers, including the five finalists, were from public schools.
