Google is displaying in-correct information in search results - Need this fixed

Google is displaying in-correct information in maps & search results about our event - & we need this fixed up as soon as possible. Our event is running from Sat 8pm 31st Dec to Sun 2.30am 1st Jan. I have searched online to see where it is grabbing this incorrect information, but can.not find any sign of this. Ive checked all my advertising sites, and they all appear to display the correct time and zone. I have checked my GMB page to, but perhaps need to change the zone or something, but cant be sure if its even coming from google my business page.

I type in "New Years Eve Melbourne" and the wrong information appears

Im looking for someone who is experienced in this area, who speaks and understands thorough english - who is confident in fixing this issue.
