Yes, you are right - that jogs my memory! Abu was quite a bit older than the other two and died at a private property not long before the other two moved to Olsen's. Tania died in 2003 - possibly from a snake [ Coastal Taipan?] bite. The area at Olsen's where they were living was quite overgrown.
Rather than Gigi staying on her own, she moved to Stardust to accompany Arna - who was also on her own at that time.
Tania certainly had "behavioural issues" which were too much for the then keepers at Perth - hence her sale to Ashtons. She was very particular about her human associates! Had she stayed at the zoo one can only speculate as to her fate.
Yes, Abu died in 2002 at a private property (not Olsens) due to age related illness. She was 67!
Tania died in 2003 due to a liver condition (she was 46). Gigi presumably lived at Olsens with Tania, and was sent to Stardust to join Arna. From there, the girls were sent to Dubbo, where Gigi died in 2019.
I'm assuming Olsen's was only a temporary home for the girls, considering it was a rather small, overgrown park. Most circuses were known to often leave some of their elephants at a park for what could be, extended periods of time.
