Hi George,
It seems that the point on the South of Melbourne comes from this address.
Olympic Blvd, Melbourne, VIC ,3001
Although it displays fine in Google Maps in the center of Melbourne, when it’s used the google maps geocode function to retrieve the coordinates it gives a different position more to the South.
You can check here in this site, enter the address and check the location is the same

The solution for this will be to delete the address you have in the Melbourne Park pin and specify the coordinates that google provide for that point.
latitude: -37.823376
longitude: 144.981159
Also made a small fix hour map function.
Let us know the result.
