Marsh who emerged as a surprise package in the inaugural IPL, scored 616 runs at an average of 68.44 as he helped power Kings XI Punjab into the competition's semi-final, where it lost to eventual IPL runner-up, the Chennai Super Kings.
However, if the Kings XI would have made it to the final, then Punjab and Shane Warne's Rajahstan Royals would have been representing India in the inaugural Twenty20 Champions League in October, forcing the 24-year-old to play for the Kings XI over Western Australia.
''I think if the crunch came, I'd probably have to play for the Kings XI,'' Marsh said today hours before he departs to join the Australian squad in the West Indies for five ODIs and a Twenty20 fixture.
''I had a few chats to Moods (WA and Punjab coach Tom Moody) over in India when we played in the semi final and I actually asked him what team I'd have to play for and he said I'd probably have to play for Kings XI and I didn't know what to say to him but that's the way it is,'' he added.
''But, luckily enough I don't have to worry about it now and I'm looking forward to playing for WA in the Champions League,'' he said.
The Warriors will be joined by KFC Twenty20 Big Bash champion Victoria as Australia's representatives in the Champions League.
Along with Rajasthan and Chennai Super Kings from India, two other teams from South Africa and England will also be there.
