Michael Cole announced 70,309 fans were in attendance for WWE Super Show-Down on Saturday. According to Dave Meltzer of the Wrestling Observer, the actual number was closer to 62,000 fans.
The Melbourne Cricket Ground can hold 100,024 fans when set-up for cricket.
WWE always inflates the attendance number, so bumping the number over 70,000 is not all that surprising. On social media prior to the event, Triple H actually undersold the inflated number, stating that it would be "over 65,000" fans.
WWE Super Show-Down was headlined by Triple H and The Undertaker meeting for what was billed as The Last Time Ever. The match also featured Shawn Michaels and Kane interfering.
