The festival, which features the likes of 50 Cent, T.I., J Cole, NeYo and Akon, was set to start in Perth this time next week, but a statement today confirmed speculation that the event was having difficulty completing the contracts for Brisbane and Melbourne legs of the festival.
The festival will be pushed to November with all current tickets still valid. There is no word on what the line up will look like, but today's statement said "Chase Records is optimistic that all artists currently promoted on the bill will be available and willing to be part of Supafest 4 in November".
Dates and venues are still to be announced.
Veterans lead this week's releases with new albums from Tim Rogers & The Bamboos (Album Of The Week) and Daniel Johns plus albums from Ella Thompson, The Vaccines and Unknown Mortal Orchestra.
