I guess the move could guarantee him a spot in the state XI, given competition will be huge in the NSW squad and, in all likelihood, Hazelwood, Starc and Cummins are more likely to be picked.The signing of Mark Cameron is a massive boost for Western Australia. Any further information on why he chose to switch states? If fit he was already in the NSW XI, and Western Australia are only giving him a one year deal.
The other signings are massive too. Rimmington and Birt both needed a change of states.
By the same token, he could lead the WA attack vs being the 2nd or 3rd NSW seamer.
