Porcelain Bathroom Tiles

I would like to re-tile my bathroom with porcelain tiles on both the floor and wall. The tiles are 60x30cm. Currently, I have ceramic tiles on the walls. I have been told that if I remove the current tiles the plasterboard will need to be replaced, which is fine. However, today I was told that I cannot hang porcelain tiles directly onto plasterboard and I need to attach a Cement Backboard (sold by Topptiles) to the plasterboard and then hang the wall tiles. Is this correct?

"You can install porcelain tiles onto plasterboard but use a primer first"

"It is likely that porcelain tiles will be above the weight limit for plasterboard (20kg/m2), not to say it would certainly fail above that weight. The correct installation of tiles above that weight would be with a hardiebacker/no more ply type cement board"

"A cement backer board is the best way to go and if you do decide to use plasterboard then it would need to be moisture resistant. Yes, you can hang any bathroom tiles onto moisture-resistant plasterboard but also depends on the weight of the tiles as well."

"Backerboard is used in wet areas as is waterproof not the whole bathroom as its expensive and unnecessary"
