The Marshall MacMahon Hotel was constructed circa 1867 and a part of it is still in use. In 1877 Wallabadah was larger than Quirindi, 15 kilometres away, but a rail connection to Quirindi reduced Wallabadah's expansion. A public school was opened in 1867 with the residence dating from 1898. In 1896 the Anglican Church of the Ascension (with 1912 additions) was established while the Catholic Church was constructed in 1910 on the New England Highway.
