All-rounder Niamh Walsh skippered the side, with clubmate Meg Thompson handling glove duties and the vice-captain role.
The pair were joined by fellow Melville players Rebecca West, Ashlee King and Kailey Wheatcroft in a WA side that struggled against high quality opposition.
The West Australians failed to claim a scalp in the six completed games up until Sunday but improved as the tournament progressed, pushing Queensland to the brink before losing in a super over decider in their sixth fixture.
Thompson and Wheatcroft have enjoyed impressive individual tournaments, Wheatcroft compiling 64 runs and Thompson taking five wickets, scoring 59 with the bat and adding four catches behind the stumps.
Captain Walsh also took five wickets and three catches in the field.
Orazio Santalucia coached WA in the tournament, which ran from January 13 and wraps up today.
“Niamh Walsh was an obvious choice as captain of the side,” Santalucia said.
“Niamh is arguably the most experienced player in the squad and is a prominent player for her club where she plays an important all-round role in the side. Meg Thompson is another of the more experienced members of the squad as well as being the voice in the field from behind the stumps.”
