The American singer has been admitted to hospital, forcing her to postpone another Sydney show just hours before she was scheduled to appear on stage.
Her Beautiful Trauma world tour was due to hit Sydney on Friday but she cancelled that first show on doctor's orders.
The singer battled through a Saturday night show but on medical advice postponed last night's concert just hours before it was due to start at Qudos Bank Arena.
Pink is also set to perform in New Zealand at Dunedin's Forsyth Barr stadium on September 1, followed by four Auckland shows at Spark Arena on September 4, 5, 7 and 8.
Dunedin Venues marketing manager Kim Barnes said this morning the New Zealand shows were still scheduled.
"We wish Pink a speedy recovery."
Promoter Live Nation said on Twitter that Pink was admitted to hospital in Sydney on Sunday night suffering from dehydration and was treated and discharged but was readmitted yesterday and diagnosed with a gastric virus.
"Pink will remain in hospital overnight, continuing her treatment and recovery," the tweet said.
Both the Friday and Monday night shows are expected to be rescheduled.
All other performances on the Australian leg of the tour will go ahead as scheduled, Ticketek said in a tweet yesterday.
Pink kicked off her latest Australian tour in Perth from July 4. She then played in Adelaide before Sydney where further shows are scheduled on August 7, 9, 11, 12, 25 and 26.
She was also due to perform seven shows in Brisbane between August 14 and 23 followed by Melbourne on August 28 and 29.
