The Lower Plenty Football Club located 18 km north-east of Melbourne in the suburb of Montmorency.
When the league folded in 1970, the club became Diamond Valley United and joined the Eastern Suburban Churches Football Association.
In the 2010 Northern Football League Second Division Grand Final played at Preston City Oval on 11 September the club was beaten by Whittlesea 9.3.57 to 9.17.71.
In 2018 Lower Plenty beat Eltham after the siren in the grand final to earn promotion from Division 2.
After changing the jumper again to be more like the Brisbane Bears (who hadn't merged yet), the club decided to wear a Maroon strip with a White outlined, Yellow V. In 2002 the club changed the jumper again to a custom strip with a Gold top and Maroon bottom separated by a Navy and White bear outline.
