The grandstand, which can seat more than 220 people, was funded entirely by the club and its sponsors.
Premier Colin Barnett and Opposition leader Mark McGowan attended the event, praising the club for its effort in completing tiered seating.
Club president Peter Carlino said he was pleased the grandstand was a reality after years of planning.
�It�s been a long time in the planning, and when you think that it�s been solely through the personal efforts of our members, it�s a great feeling of satisfaction,� he said.
�It takes us to another level, where our supporters can enjoy the games.�
Mr Barnett congratulated the club on encouraging people to give soccer a go.
�Football is triumphing in this country and in this State; there are more than 76,000 players from all ages and grades in Western Australia, more than AFL and netball,� he said. �I want to compliment the club on the fact that you�ve got 450 players, 700 supporters and you�ve done an extraordinary job, young players as well as encouraging women into the sport, so it�s a fantastic community base.�
Mr Barnett thanked the club for its role in the State Government�s Sport for Kids initiative.
�One of the most important programs is Sport for Kids, and I know this club has been particularly supportive of it,� Mr Barnett said.
