According to the official WWE.com listing for the upcoming WWE Super Show-Down event, the show will start at 7pm local time on October 6th in Melbourne, Australia.
If WWE Network plans to air the event live, that would mean the show will begin at 5am EST / 2am PST on October 6th, however, WWE has yet to announce whether or not the show will air live.
In related news, The Wrestling Observer Newsletter reports that while numbers have yet to be reported, advance ticket sales for WWE Super Show-Down are said to be good, but good enough to where the event will sellout without WWE having to paper the crowd. The arena in Melbourne is set up for 80,000 fans, and if WWE is able to draw that many fans they will likely announce an attendance figure of 100,000 people.
WWE has been pushing on TV recently that the show will take place in front of 70,000 fans, which is a reduced number from the 80,000 fans WWE initially claimed the show would have.
The latest match announced for WWE Super Show-Down is Cedric Alexander vs Buddy Murphy for the Cruiserweight Title, and you can check out the rest of the confirmed event card at this link.
