Ceiling Patching Question

I need a new exhaust fan in my room but the hole is 300mm and I want an inline fan which only needs a 280mm cutout.. They left the cutout above the hole but am I better off cutting a square bit of gyprock secured to batons and taping the seams rather than reinstalling the 300mm cutout and just plastering the circular seam.

Square.. then get some furring channel.
then cut and run the two pieces either

side just off the edges by 50mm screw up

screw in new square then paper tape not

that mesh shit and at least 3/4 of a trowel

either side of joins as your treating it as

a butt join ! Not like a recessed joint .
two coats of base at least to flatten it

out then top coat ! Sand if still not happy

retop till flat .. good luck cheers pirate
