Last week it was Telstra Tower turning a suddenly fashionable green, and this week it was the turn of the Department of Treasury building in Parkes.

A keen Raiders fan, Steve French, works for the department and helped arrange the light show, captured on Wednesday night by photographer Nigel Hawkins.

Canberra fans will be well and truly outnumbered on Saturday night, when the Raiders and South Sydney meet in their first finals clash since 1989. Supporter buses will carry hundreds of Raiders fans to the game at ANZ Stadium.
