I finally found an article with very detailed times and dates:
“SURELY, if you loved them, you would have immediately notified the medical authorities about there being a possibility that the foraged mushrooms had gone into the container with the Chinese mushrooms?” said Dr Rogers. “Well, I didn't,”...

But, on her own evidence,
Erin Patterson knew she had been foraging for wild mushrooms prior to the lunch when Simon phoned her at 11.18am and 2.30pm on Sunday, July 30, telling her that his parents, Don and Gail Patterson, were sick in hospital.
On the evidence of Lisa Shannon, the after-hours coordinator at Korumburra hospital, Don and Gail Patterson presented at the hospitals’ urgent care department at 10.10am on Sunday, July 30, 2023.
The clock was already ticking on their exposure to the deadly amatoxins in amanita phalloides mushrooms,
but it wasn’t until sometime after 6.50am on Monday, July 31 that they were finally administered the potentially life-saving amanitin antidote, Silibinin, the most widely used inhibitor of the effects of death cap mushrooms.
Even then, doctors were still unsure of the source of the poisoning.
ALSO, There is this:
Dr Morgan called Dr Douglas again at 11.30pm Sunday, and he undertook to contact the senior toxicologist, Dr Yit Leang, she said the specific antidote for amanita phalloides toxicity Silibinin wasn’t indicated at that time.
“Based on the story that we knew so far, Dr Leang's advice was that at the moment there wasn't enough evidence, it wasn't clearly cause and effect of having had a specific mushroom called amanita phalloides, the death cap, so at that point the specific antidote to that wasn't indicated at that stage,” Dr Douglas told the court, during his evidence on Day Seven of the trial.
....snip....
At 6.30 am, Dr Douglas received a further phone call from Dr Morgan, advising that Don’s clinical state had worsened even further and now Gail was showing similar signs.
Dr Douglas advised her that she should start getting the process running to start some Silibinin, as per the Austin clinical guidelines.
THE NEXT MORNING THEY ASKED EP ABOUT THE MUSHROOMS AND SHE LIED
Just after 8am on Monday morning, July 31, 2023, on her initial presentation at Leongatha Hospital, Dr Chris Webster asked her as much.
“There's a concern of death cap mushroom poisoning,” Dr Webster told the court he had said to Erin in the Urgent Care Centre that morning.
“Where did you get the mushrooms?”
“Woolworths,” was allegedly Erin Patterson’s one word reply.
....snip....
SO AT AROUND THE EXACT SAME TIME THAT THE FIRST 2 GUESTS WERE RECEIVING THE ANTIDOTE, EP ARRIVED AT THE HOSPITAL AND LIED ABOUT THE MUSHROOM SOURCE.
