Round 1: Bulldogs vs Double Blues

Until I checked the AFL draw today, I thought the Port vs Kangaroos match on April 1st was to be played on Saturday afternoon at AAMI.
Why did the SANFL program this unique game at Hamra Homes Oval to directly clash with the AFL game?
Will cost the SANFL at least 3,000 spectators and should have been played on the Friday NOT in a direct clash with a Power game in Adelaide.
