Sydney Olympic Park. $7.7m playground

NSW Premier Kristina Keneally has announced a $7.7 million investment in a “mega park” at Blaxland Riverside Park, which adjoins Sydney Olympic Park. The facility will take up an area larger than four football fields and is set to triple the park's capacity to 4800 people a day and turn Blaxland Riverside Park into a mega-park for Western Sydney … this park will take the pressure off the nearby Bicentennial Park, which at peak times can be difficult for families to find a place to play," Ms Keneally said. Families can expect to be able to use the playground from as early as April, with the park expected to be completed by early 2012.
