The former West Coast Fever player was awarded the Jill McIntosh medal at the Netball WA awards night following an excellent season, in which she was also named at goal defence for the league�s team of the year.
Known for her toughness and leadership, Gilmore has played 83 games in WA�s top league.
She arrived at the Warriors as a playing assistant coach this year after a season with the Adelaide Thunderbirds in the professional Trans-Tasman Netball League.
Before her Adelaide stint, she had featured 69 times for the West Coast Fever up to 2013.
Outside of the Warriors in 2015, she captained the Western Sting to a bronze medal in the Australian Netball League, which is a tier below the professional level.
Netball WA chief executive Simon Taylor labelled Gilmore an �incredible ambassador� for netball.
�Andrea is a talented player and a natural leader, and demonstrated those abilities throughout both the WA Netball League and the Australian Netball League in 2015,� he said.
West Coast Netball Region president Trish Robinson and Warriors veteran Lisa Millman were also honoured at the awards ceremony.
Robinson was named Volunteer of the Year, while Millman was recognised as the league�s games record holder having amassed 266 appearances.
Warriors talents Numi Tupaea and Jess Eales were named alongside Gilmore in the team of the year.
