Not even going to be in the same state and very keen to throw down for this.
In terms of logistics would it be easier to buy one normal size cake and decorate that to pimp spec to have presented on stream/outside WCS hours and then have 300+ cupcakes made up for everyone to chow down on?

Logistically easier to just direct people to a table to collect a cupcake than present giant cake cut it up and all the weird gripes people have with food handling. Then you have the spectacle cake around a bit longer for photo ops n general admiration. Plus I assume the organizers want this gesture to be a short one.

Thanks to the boom in baking thanks to TV chefs n such I am sure there is some kind of cupcake king or queen in Sydney and if you get in early *now* 350/400 would be easy as.

Edit: Sydney Based do bulk orders and they deliver!
