Wooroolin Provisional School (also known as Wooroolin Lagoon Provisional School) opened on 18 February 1901 and become Wooroolin State School on 1 January 1909. The section of the Nanango railway line from Wondai to Kingaroy opened on 19 December 1904, with Wooroolin served by the Wooroolin railway station (). That section of railway line was closed in 2009. Track removal occurred in 2014 making way for the new
Kingaroy-Kilkivan Rail Trail. Wooroolin Presbyterian Church was opened in 1909 with the first wedding held in the church in December 1909. It subsequently closed and has been used as a restaurant. It is at 1 Alexander Street (). In August 1913, the Catholic community in Wooroolin accepted a tender from B. Robinson to construct a church for £206. On Sunday 9 November 1913, St Patrick's Catholic Church was officially opened by
Archbishop James Duhig in the presence of 400 to 500 people, 300 of them came by a special train provided for the occasion. It was and built from timber in the
Gothic style at a cost of £330. It was on a site on a hill overlooking the town at 24-26 Frederick Street (). It has since been demolished. St Andrew's Anglican Church was officially opened on Sunday 20 November 1921 by Archdeacon Osborn. It was a timber church capable of seating 50 people. It celebrated its centenary on Sunday 21 November 2021. Wooroolin West Provisional School opened on 2 April 1929; it closed at some time between 1944 and 1949. After successive floods in
2011 and
2013, the wetland burst its banks and Wooroolin was flooded for the first time in
recorded history. As at 2015, the wetland was still completely full and resembled a large, shallow lake. Due to a bad drought in later years from 2015 to late 2020, the wetlands drained completely. In November 2021, 305 ml of rain fell across the area in and filled up the wetlands in a matter of weeks for the first time in years. == Demographics ==
