If the owners of Erina Fair don't want the signs with that message then I'm guessing that's their call legally? I suppose it's a privately owned space. I'm sue they wouldn't want "the greatness of his power Allah is alive" sign there either.
You can do what you want however on your own privately owned space.
At any rate people need to grow up from all this ridiculous religious rubbish. There is NO mention of Easter in the bible or any mention of chocolate, rabbits etc etc. It's all just plagarised nonsense.
