my friend, china passport and went to zhuhai, no visa at macau,

but he is SPR, so has NRIC,

u may check with any travel agency to get the absolute correct info. they do consulting in order to sell air tickets or travel packages.

Hope it helps

that friend (SPR) is the same like you, but he visited macau and only drop by hongkong, no need visa.

not sure yours, but suggest bring along everything to prove that you are a resident of singapore, otherwise, may have troublesome when going back to sgp.
