I'm a little bemused by the fact that the only mention of West Australian teams in "Great Domestic Sides of the Past" is in the context of two Shield finals (v Queensland 80/81 and v NSW 95/96).
WA had three talent-laden sides that won back-to-back Shields (one with 3 in a row).
71-73 Included test cricketers in John Inverarity, Ross Edwards, Graeme Watson, Rod Marsh, Tony Mann, Dennis Lille, Graham McKenzie, Bruce Yardley, Bob Massie, Sam Gannon and Tony Lock.
A bit top heavy with bowlers but Derek Chadwick (9 first class centuries), Jock Irvine and all-rounder Ian Brayshaw were no mugs.
76-77 Included test players in Bruce Laird, Wally Edwards. Kim Hughes Craig Serjeant, John Inverarity, Trevor Chappell, Rod Marsh, Tony Mann, Bruce Yardley, Dennis Lillee, Terry Alderman, Mick Malone and Wayne Clark
Throw in all-rounder Rob Langer into the mix and you have an impressive line-up.
86-89 (3 Shields) These teams included test players Geoff Marsh, Graeme Wood, Mike Veletta, Kim Hughes, Tom Moody, Tim Zoehrer, Bruce Reid, Terry Alderman, Chris Matthews, Tom Hogan, Vic Marks and Alan Mullally.
Add Ken MacLeay, who played in ODIs for Australia and a more than competent bat in Wayne Andrews and one can see why this side was so dominant.
I'm not saying that some of the past NSW and other eastern seaboard sides aren't as impressive on paper. I'm just adding a bit of west coast balance.
