The first stage of the Casey Fields development cost $4.2 million and opened on 29 April 2006. The facility consists of five grassed ovals: the main and northern-most oval is known as the VFL Oval, and is used exclusively for Australian rules football. In 2005, the VFL's Springvale Football Club had been struggling financially and was hindered by the rundown condition of its home ground in Newcomen Rd, Springvale. To attempt to financially secure its future, the club and the City of Casey came to an arrangement for club to move to Casey Fields. The club moved there in 2006, changed its name to the Casey Scorpions, and played its first match on the oval against Box Hill on 29 April 2006. In 2009, the Melbourne Football Club and the City of Casey entered a 30-year partnership. The partnership which saw Melbourne establish a training centre at Casey Fields on the VFL Oval and its pavilion, which was expanded for the partnership. The two parties established a number of community-based programs together, and Melbourne entered a reserves affiliation with the Casey Scorpions from that season. The Oval has been the primary home ground of Melbourne's AFL Women's team since 2017. In addition to VFL matches, the VFL Oval has hosted NAB Cup pre-season regional challenge matches. The record crowd of 10,099 set in 2007 in a match between Hawthorn and Essendon. The ground also hosted many of the games played during the 2008 and 2009 AFL Under 18 Championships. The VFL Oval has a seating capacity for only a few hundred spectators, with terraces and hills around the ground providing the rest of its capacity.
Other facilities
In addition to the VFL Oval, Casey Fields has four other ovals which are used for Australian rules football in winter and cricket in summer. Ovals No. 4 and 5 and their adjoining pavilion serve as the home ground of the Casey-South Melbourne Cricket Club, which competes in the Victorian Premier Cricket competition. The South Melbourne Cricket Club moved to Casey Fields and changed its name to Casey-South Melbourne prior to the 2006/07 season. Local Cranbourne football and cricket clubs also use these four ovals. Casey Fields includes a criteriumcycling track, which is often used by cyclists and is the location of two different rounds of the Victorian HPV Series every year. The complex also has an athletics centre, netball courts, tennis courts, rugby fields, a golf practice cage, and fishing lake. Since the 1990s it has been proposed that a Cranbourne East railway station be built adjacent to the complex, on a short extension from the current Cranbourne terminus of the former South Gippsland railway line. This has not yet eventuated. The only current alternative is the "Train Link" bus from Cranbourne station to New Holland Drive, and then a 15-minute walk to the complex.
