The groups Manager Paul Field has since given fans an update on Page's condition, revealing he is in recovery.
Field told 7News that the hospital “worked with him he is in good care and hopefully with the right treatment he will be fine”.
Meanwhile a photo of Page in hospital giving the “thumbs up” was posted on the band’s official Facebook page Saturday afternoon, with a message.
“We have visited Greg this morning and he wanted to thank everyone for their well wishes. Greg and his family are so grateful for all the messages of love and support from fans around the world,” read the post.
It continued: ”Greg’s main concern was that the show tonight should go on. Greg will not be performing tonight but we will have some wiggly friends jumping in to help out and make it a great show.
”Let’s raise the roof tonight and do it for Greg whilst raising funds for the Australian Red Cross and WIRES.”
Fans were quick to express their heartbreak at the news, wishing the entertainer a speedy recovery.
“Thinking of Greg and all The Wiggles at this time. Greg stepped out to support others - we acknowledge his courage and compassion," one fan wrote on Facebook.
Another also took to Facebook, writing: “How terrible. Doing something out of kindness, usually the way. Best wishes for a full and speedy recovery.”
Page was on stage with Anthony Field, Murray Cook and Jeff Fatt when the incident occurred.
The Yellow Wiggle bid farewell to the children's band in 2006 due to health issues and later returned in 2012.
