The list signals a shift in the powerbase of Australia cricket with West Australians now having the largest representation.
Four players are from New South Wales, South Australia and Victoria each have three, while Test captain Paine is the sole Tasmanian on the list.
Western Australian Cricket Association CEO Christina Matthews said it's rewarding to see long term goals like this achieved.
"For WA to have the greatest number of players on the Australian Men's contract list is a fantastic testament to the program we've been running over the last four or five years," Ms Matthews said.
"It's always been an aim of Australian cricket that states are primarily producing Australian players, and for us to have leapt ahead of those bigger states is very exciting for our program and is a testament to the investment we've put in to developing our top players."
The Australian Women’s contract list see the return of veterans, Western Fury captain and vice-captain Elyse Villani and Nicole Bolton.
