Member for Ipswich Rachel Nolan MP said Ms Smith and Ms Brown had been crossing supervisors since 1990, keeping thousands of children safe when crossing the roads.

"It's a great contribution to the community and they deserve to be honoured for it," Ms Nolan said.

"Crossing supervisors are protecting the lives of children all over the state every school day and I know Queenslanders are grateful to all of them.

"In the 26 years the school crossing scheme has been in operation, there have been no fatal crashes on supervised crossings and that's largely due to the dedication of people like Ms Smith and Ms Brown."

Ms Nolan said when the scheme started in 1984 there were 353 supervised crossings at 205 schools.

"Today, there are 1,176 crossings staffed by 1,873 supervisors at 640 schools," she said.

"The provision of supervised school crossings is a partnership between the Queensland Government, local councils and, most importantly, the school community.

"School crossing supervisors play a vital role in protecting and educating children about road safety as they travel to and from school.

"The effort they put in, often in difficult conditions, is to be admired - for Ms Smith and Ms Brown to maintain this effort for 20 years at the same school is quite extraordinary," Ms Nolan said.

"The pair have watched school students' progress through the years to high school. They have even seen former students returning as parents, walking their own children to school.

Ms Smith and Ms Brown each received a service pin and Certificate of Recognition from the Queensland Government for their valuable service to the community.

Ms Nolan said everyone had a role to play in encouraging road safety around schools.
