We’ve just recently learned from our contact at Turner Asia that Toonami Australia which was reported to be launching back in July 2016 has been canceled, Toonami Australia ran from September-December 2016 and aired Fri-Sun, 10pm-12mn.
Our contact said there was no specific reason that it was canceled that their schedulers like to offer viewers something different, depending on the content available to them on hand. Sometimes these are long term changes, sometimes not.
In Australia, Cartoon Network is a 24-hour kids and family channel, so it’s really not the same as the CN/Adult Swim/Toonami arrangement in the US. Our contact also said there’s a chance Toonami can come back in Australia but no plans as yet that they can confirm.
