The South West Football League have locked-in the 2017 pre-season fixtures with three venues set to host games on Saturday, April 1.
Bunbury Bulldogs will host Collie, Carey Park and Brunswick-Leschenault at Payne Park with each side to play two games.
Harvey Bulls will host Eaton and Busselton in a round-robin competition at Harvey Recreation Ground while Augusta-Margaret River will host reigning premiers South Bunbury and Donnybrook at Gloucester Park.
The SWFL umpires are also set for a change this year with the league moving to the national umpiring colours of grey and green after many years in orange and black.
A move by the AFL to have all umpiring associations in the new colours will see the locals don green shirts and socks and dark grey shorts. For the first time, goal umpires will also move away from black pants in favour of grey.
It is just the fifth change of uniform in 60 years for the umpires, who wore all white until 1983.
