The "On Our Own" singer was slated to begin the series of concerts, along with Naughty by Nature's Treach and Kay-Gee, at Brisbane's Eatons Hill Hotel Mar. 18, followed by two dates in Sydney slated for Mar. 20 and 21, according to the outlet Ticketek.
The Sydney shows have been rescheduled for May 28 and 29, and the new tickets will be up for sale Feb. 27. Other shows include a May 26 date in Gold Coast, and May 30 in Melbourne.
As RadarOnline.com previously reported, the former New Edition singer has been a constant presence at Emory University Hospital for the better part of a month, since Bobbi Kristina was found face-down and unconscious in a bathtub in her suburban Atlanta home Jan. 31, leaving the 21-year-old daughter of Brown and the late Whitney Houston brain dead and surviving on life support.
