I couldn't find the info earlier but here it is now:
In TNA's 2nd week on Australian TV, iMPACT out rated both WWE's RAW and SmackDown. It's also interesting to note that SmackDown beat RAW this week. Below are the numbers from the listing for the Top 100 Pay Television Programs:
28. TNA IMPACT 43,000
38. WWE SMACKDOWN! 38,000
44. WWE RAW 36,000
Although TNA did beat out WWE in the ratings in Australia the week before WrestleMania, for the next two weeks, TNA was far behind Raw and Smackdown. For the week ending 4/5, Smackdown was No. 22 in Pay TV with 106,000 viewers and Raw was No. 23 also with 106,000 For the week ending 4/12, Smackdown was No. 12 with 123,000 and Raw was No. 15 with 119,000 viewers. TNA was not in the top 50 either week
