For Boomerang worldwide, see Boomerang (TV Channel).
The Australian version of Boomerang was launched in March 2004 as part of the Foxtel Digital launch, with a lineup very similar to that of the UK version. It started previously as a programming block on Cartoon Network, one every weekday morning, and one every weekday evening. On weekends, Cartoon Network had "Boomerang Character Of the Month" - a two hour block that aired Saturday and Sunday evenings and featured a particular Boomerang show for the two hours.
