Mars Stadium is a 11,000-capacity outdoor sports venue located in the Victorian regional city of Ballarat. Stage one of the venue's redevelopment was completed in late June 2017 at a cost of $15m. The ground has been transformed with construction of a new 5,000-seat grandstand, 50 sq/m video scoreboard, new lighting, as well as the resurfacing & realignment of the playing surface, which is now the same dimensions as Marvel Stadium. The North Ballarat Sports Club is located at the ground which features tables overlooking the playing arena.
Mars Stadium was previously known as Eureka Stadium and was the home ground of former-VFL team North Ballarat Roosters. It hosted its first AFL match for premiership points in August 2017 and continues to host two Western Bulldogs home games each year. New A-League club Western United will also play some home matches at the venue until their new stadium opens, while it'll also host a Super Rugby fixture for the first time in 2020.
In 2019, it was announced a further $6.6 million will be spent to upgrade Mars Stadium, with new entrances and ticket boxes, covered areas, permanent bathrooms and increased accessible seating in the Western and Eastern stands to be built.
