Janette Melvin began her playing career in the very early days of Women’s football in Victoria. She captained Melton in the inaugural season of the Victorian Women's Soccer Association (VWSA) competition, claiming the Championship with a thrilling win over Greensborough in the Grand Final. She would ultimately become a staple of the Greensborough team which was recognised as the powerhouse club throughout the early years of the VWSA competition, and were virtually unbeaten for a decade throughout the 1970's and 1980's.
Melvin was a state representative for fifteen years between 1974 and 1988. During and after Melvin's representative playing career she became heavily involved with the development of the women’s game in Victoria. Melvin pursued her coaching license and along with former Matilda Shona Bass they were recognised as the highest accredited female coaches in Victoria.
Melvin coached junior representative Victorian teams between 1984 and 1986, was the Victorian Youth Coach in 1990 and Assistant Senior Coach in 1991. Her dedication to junior development and outstanding contribution to the development of women’s football in Victoria is recognised in the naming of the Hoar-Melvin Trophy, introduced as the award for the most valuable junior state team player.
Melvin continued to coach senior women’s teams, notably the South Melbourne Women’s Premier League team. In 2001, having already been recognised for her contributions by Women’s Soccer Victoria, she was awarded with Life Membership to the Victorian Soccer Federation, now Football Victoria.
