But you only fix hardi around the edges?, what centres?.

Hardie has pre marked holes Russell, edges and middle,it's just like plasterboard a ceiling in 4x3s ,same amount of screws and staggerd the same,, I just use a no more ply knife to cut straight and a grinder for awkward cuts , outside obviously [emoji15]

Roughly 35 screws for a sheet of Hardie, fixed on 200/300 centres.

Think I'm going to go with ply. I've not seen hardi backer done, until then I'll go with what I know and just screw a 4" centres. I'm not saying ply is better Im just not sure I'll do hardi backer right until I've seen someone do it.

Once you have laid the boards and taped the joints, it should look something like this.

I got told off someone from James hardie that you only need 12 screws per board!!!!

They shouldn't be giving out that advice, this is from the product & installation guide.
