THE old classroom bell will ring in the ears of former students once again today, as Maryborough Central State School celebrates its 150th year.
Committee spokeswoman Janet Olds said thousands of people were expected to visit as Queensland's oldest public school celebrated its big birthday.
"There were 4000 for the centenary, so we are hoping for another good crowd," Mrs Olds said.
"People are coming from Far North Queensland and Victoria, and it's catered towards the whole community - not just former students."
With registrations starting from 11am, there will be a roll call and class photographs of former students from the 1930s through to those who graduated in 2000 onwards. After a performance by the Central Strings and Concert Band, the Hunter family will make a memorabilia presentation to the school at 12.35pm.
Queensland Governor Penelope Wensley will plant a commemorative tree, launch the time cannon and conduct a tour of the Kent St school, before leaving on the Mary Ann train.
Mrs Olds said there would be interactive displays, memorabilia and performances to keep guests entertained.
"There will be a wheelwright demo, which will be really interesting, and people can also try out their handwriting with copy-books and slates," she said.
"The original Sauer's Pie Cart will also be there."
The day will be rounded out with performances by the Clan Highlander Swordsmen,
Maryborough Excelsior Band, Scottish and indigenous dancers, and vocal ensembles.
A commemorative book compiled by Dianne Humphreys and David Clark will also be available.
Anyone associated with the school is invited to meet at the Carriers Arms Hotel on Alice St at 6.30pm for an informal meal with friends.
