The Diamond Valley Women’s Amateur Athletic Club (DVWAAC) was formed in 1958. It was affiliated with the Victorian Women’s Amateur Athletic Association (VWAAA) and competed in their Inter-club competition. Willinda Park in Greensborough was the training base, and remains so to this day. In 1958 it was a grass track with limited facilities. The uniform was a green top with a black diamond on the front with the letters 'DV' in white.
In the club’s inaugural year there were 34 registered members and it finished 2nd on the ladder (out of 8 teams) in 'J' grade. In the final Preston/Reservoir defeated Diamond Valley 27-12. During that season, two grade records were set by P. King. The 65 yards Hurdles was run in a time of 10.3 (14/02/59) and the High Jump cleared at 4'4'' on 13/12/59.
For the next season, registration numbers dropped to 25. Junior teams were entered in 'E', 'G' and 'H' grades. They finished 4th, 1st and 3rd respectively, with each grade consisting of 8 teams. Best performances included G. Roschelle with a javelin throw of 95'8½" and discus throw of 94'1" (both E grade), B. King 4'4" in the High Jump (G grade) and S. O'Keefe spinning the discus 80'4½" (G grade).
In season 1960-61 registration numbers were again down, this time 23. The juniors in E grade won that division, while the J grade juniors were 2nd. Grade records for the season were B. Poulson 9.2 in the 75yds and 12.1 for the 100yds, with C. Anthony 9.9 in the 65yds Hurdles. D. King jumped 4'8" in F grade. Diamond Valley competed in the Mabel Robinson Shield (junior competition) and was 11th out of 15 teams, while for the sub-juniors they contested the Mabel Moad Shield to be 15th out of 17 teams.
Membership increased for 1961-62 to 35. The senior D grade were 5th, while for the juniors the B grade was 7th, H grade 2nd and J grade 4th. Again all grades consisted of 8 teams. 1962-63 was not as successful with the senior team down to E grade and coming 4th, while the juniors in C grade were 8th and the F grade were 7th.
With falling numbers the club merged with Broadmeadows for the 1963-64 season. Collectively they had 57 members, almost double the numbers of previous seasons. With the combined strength the team was far more competitive with seniors in C grade and E grade (no results known), while the juniors were in B grade (5th), D grade (2nd), E grade (5th), G grade (6th) and H grade (7th). In the D grade final, the juniors lost to Oakleigh 57 - 48
The Diamond Valley - Broadmeadows merger continued through to the 1965-66 season where the combined membership had fallen to 37 (it was 43 in 1964-65). For the 1966-67 season, Diamond Valley and Broadmeadows had separated, and the DVWAAC competed with 33 members. For the late 60s and early 70s the membership hovered between 30 and 44 (1968-69). The pattern was always that the membership jumped up after an Olympics, a trend that remains to this day.
In 1968 the DVWAAC competed again as a separate entity. Registration numbers varied between 20 and 40 up until 1985. Women’s and men’s athletics were conducted by separate associations until the early 1980s. Women’s competition was conducted separately, with a grass track at Royal Park being the home of the competition. The uniform was a green top with a 'DV' symbol on the front, and black shorts.
A men’s club was formed in 1978 (Diamond Valley Amateur Athletic Club - DVAAC). David Irvine, who was previously a member of Ivanhoe Harriers, was the first President of this new club. The men adopted the uniform style of the women's club. Registration numbers peaked at around 60 soon after creation, but then sank to around the 30 mark in the early 1980s.
In 1985, the men’s and women’s clubs combined to become the Diamond Valley Athletic Club. This came about as the VAAA and VWAAA merged in the early 1980s to become the VAA (Victorian Athletic Association). Also the small membership numbers of the two clubs encouraged the merger to avoid the obvious duplication of effort. Summer competition was held at the Doncaster Track.
During the seasons 1989 - 1991, Diamond Valley formed a Combine team called 'Plenty' with Old Paradians and Keon Park for the Cross Country season. Club numbers were low, but the combined team enabled the clubs collectively to field teams in a number of under-age and senior grades. The club continued to field teams in the summer competition as Diamond Valley.
Membership numbers varied over the next 10 years, and was so shaky at times that the club’s continuation was in doubt at times.
A revised uniform was adopted in the mid 90's. It was still a green top, but now featured stylised black and white stripes on one side. For the women two piece suits were designed with the same theme as the singlet tops.
A steady improvement in the administration of the club from the early 1990s saw membership numbers gradually rise. Great improvement came to the club in the social and on-field performances. In the winter season, the women competed in Division 1 for a number of years, before falling back to Division 2 in 2001. The men gradually improved their standing to be in Division 2 with a 3rd placing in this Division in 2001. The Track & Field season produced many Venue premierships - including the Division 1 women who won three Division 1 Venue premierships in 4 years (1997/98, 1999/2000, 2000/01). The Men won their first Division 1 (formerly B grade) premiership in 1999/2000.
A peak membership of over 125 was achieved in the 2000/01 season. This was a very successful season with 13 teams making the Venue Finals at Box Hill which resulted in 3 Venue premierships (M4, M18 and W1), and the club's first Association premiership (M4).
The club uniform had another make-over in 2004. Based upon the existing design, a yellow splash was added to one side that merged into the existing green. This uniform was designed in conjunction with Diamond Valley Little Athletics, where it became their centre uniform as well.
Improving the club's coaching stocks became a high priority in the new century. Bernie Smith assumed the role of coordinating this task, and with the help of many the club assembled a fine collection of coaches.
Long serving President, Max Balchin, finally took a well-earned rest in 2005. Max had been at the helm of the club for 15 years, and together with Lyn Davis was instrumental in resurrecting the club from a small athletic club to one of the largest clubs in Victoria.
A new membership record of over 160 was set in the 2006/07 season with over 145 registered members and a large number of 'associate' members.
Currently the membership is reaching close to 300 which made the club the second largest club in Victoria in the 2014-2015 summer season!
