Partly correct.
It was never announced publicly by Brad Hazzard, Gladys Berejiklian, Kerry Chant nor NSW Health. It finally emerged in late June when a reporter asked it as a Friday 11am briefing. Brad Hazzard would not answer the question asked & refused to allow the reporter to challenge him, instructing the reporter that 'you've had one question, that's it."
Hazzard nominated another more friendly reporter, who disappointed him by asking him to answer the question. Brad again deflected.
Next reporter, same question. Deflected. 4th reporter quite loudly & abruptly asked for the question to be answered. Deflected. 5th reporter, again picked by Hazzard demanded it be answered, "Can you please confirm if that report from the limo driver is true?".
Worth looking at the video (I'll try & track down the date), Gladys glares at Hazzard & all Hazard says is "Yes, that's correct."
IIRC the briefing was shut down very shortly after.
Original question came as (IIRC), "Can you please confirm what the limo driver told me when I interviewed him yesterday, that NSW Health re-contacted them a few days after the intital days of interviews and asked to conduct more extensive interviews. When the limo driver asked why as he'd already spent many hours - the response was, no we want to speak more with your wife. He then asked why and was told that both of the FedEx aircrew had tested negative so he had not caught it from them. NSW Health now believed that he'd caught it from his wife who had previously been designated case #2."
BTW The police investigation confirmed the limo driver had actually not only complied with all requirements but had gone further in his precautions than required (confirmed by CCTV footage obtained from more than a dozen locations) before, arriving, during, leaving the airport pickup and before, arriving, dropping off & leaving the hotel.
Also not ever publicly mentioned at the 11 am briefings.
