Cheers Guys, I managed to put all 21 boards up in the end just by using screws and some extra noggings using about 15-20 screws in each,

bloody heavy, but hopefully worth it, at least I now know it should bear the weight of the tiles and addy and grout.Just got to tape the joins and cover with addy tomorrow.
Thanks.
Vinnie.

Partition wall is warped badly my builder recommends we take down existing skimmed plasterboard and replace with osb board to bring out from warped joists and then use a hardie backer board on top to give a flat wall for tiling as going to be using 300x900 ceramic tiles which are 22kg metre square. This maybe ott but best way any thoughts welcomed thanks
