If it is tiled finish it should be fastener only fixing with close spacing along the edge, that will pull the sheet in.

So, metal framed house. Renovating bathroom. Doing the walls, I notice that when the wall board (aqua check) is going in, it doesn't touch the metal noggins. The board is attached to the uprights but because the noggins fit inside the metal frame, there is a small gap when the sheet is in place. Given the join between bottom and middle sheets will be tiled over, do I need to fill the gap between the noggin and the shee with something? I have cut wooden noggins to put in but wondering do I need to bother?

The first pic shows the plasterboard up against the upright framing. With the sheet attached to the uprights, there is a small gap between the plasterboard and the noggins across the wall. Do I need to pack these gaps before I attach the top sheet of gyprock?

Sorry was misunderstanding where the gaps are, but as the plasterboard needs to be attached by fasteners only any uneven faces in the attaching frame will result in an uneven finished surface.
Uneven surface for tiling can create issues particularly with larger format tiles, small tiles may not be so noticeable and adhesive can take up small differences.
Best is to get the finish surface as flat as possible.
All you need to do is put some plaster glue at the recommended spacings on the cross pieces. Its what 1.2-1.6mm diff, you get bigger variation in wood.
Cool. Will fill it with glue. Thanks.

The installation guide is very clear on the requirements. There is no need to attach to noggins and the guide only mentions fastening to studs. Just make sure the noggins aren’t sitting proud of the studs.
Doovalackey - there is a WARNING in the installation guide not to use stud adhesive with tiled wet systems (in CAPITALS!):

Better to have nogs sitting in than sitting out. No reason to screw sheeting to nogs whether its steel or timber. Its fine.
