Field days commenced at Dowerin in September 1965; they claim to be the longest established field days in Western Australia. They are now known as the "Dowerin GWN Machinery Field Days", naming rights having been granted to regional television broadcaster Golden West Network (GWN) since 1992. The Dowerin Field Days are traditionally held during the last week of August each year over a three-day period, attracting over 40 000 people, with over 600 exhibitors. Since 2008 the Dowerin Field Days has reverted to the original 2 days.
