A Combined Training Centre (CTC) was established at Toorbul Point (now Sandstone Point) in mid 1942, in order to train army and navy units in amphibious warfare. A training camp with jetties, slipway, mock ship, workshops, lecture rooms, messes, accommodation and camp sites was established along the shoreline either side of today’s bridge to Bribie Island. The CTC was used by both the US and Australian armies and navies, including the 7th Division 2nd Australian Imperial Force (2nd AIF), Australian 4th Armoured Brigade, US 1st Cavalry Division and the US 32nd and 41st Infantry divisions. After boarding vessels at Toorbul Point, practice landings of men and vehicles were carried out on the beaches of Bribie Island.

Today, little remains of the CTC. The campsite extended along the shoreline of the Pumicestone Passage northwest of the bridge, and north of the Bribie Island Road, as far as the northwest end of The Circuit, while jetties continued along the shoreline past the marina and Kai Ma Kuta Drive. Southeast of the bridge, the camp site continued around the shoreline of Deception Bay about as far as Sunbrite Court. Traces of the camp’s internal road remain southeast of the bridge.
