[5] When construction was complete, railway staff, including a stationmaster and an assistant were appointed to Wirrega in November 1912.
[6][7] Wirrega was named as a potential terminus for a light railway to Kingston SE or Lucindale, but nothing came of the proposal.
[9] On 19 January 1938, a large scrub fire was alerted to by the signalman at Wirrega, and damage was caused to telephone infrastructure and sleepers, delaying some trains.
[10] Later works during the 1950s-1960s included the construction of concrete grain silos so that wheat being loaded onto trains at Wirrega would no longer need to be bagged, and a new small brick building at the station similar to those that still exist at Coomandook, Coombe, and Culburra.
[15] The station yard retains 3 tracks, including the abandoned goods siding, a 1550m passing loop, and the mainline.
