Hope someone can give some advice on building materials.
We are building a 2 story house in Adelaide and plan on using Hebel 75 mm autoclaved aerated concrete for the lower level and renderpanel walling system for the upper level.
I have recently heard that the Hebel is prone to joint swelling and problems down the track.
Any information on foreseeable problems or issues would be great.

I have not seen hebel swell.... it is typically used to form up shower trays, which is quite a wet and humid environment, Hebel is a concrete product and as such shares many of concretes plusses, with out the added weight.
I am a big fan of Hebel as a building product. I can absorb water and as such needs to be sealed correctly, but the joints should not swell

We did exactly the same as you
Hebel on the bottom
foam on the top
the whole lot rendered. I installed the hebel myself, the only problem I had was one slight crack in a corner where I didn't put an expansion joint in where I was meant to, which was easily fixed. I left the stuff un rendered for 3 months for this purpose.
great stuff, good thermal qualitys, beautiful rendered finish perfectly straight and is good at noise insulation.

I would consider using the powerfloor to the upstairs as well that way the floor will match your ground floor in sound and the 'solid' feel. I have used hebel for upstairs flooring (for brick veneer houses on concrete slabs) a number of times and the clients have been happy. Like any 'system' product the key is to install exactly as per manufacturers req so that warranties are not voided.

I'm sure this hairline crack along the joints will still be there in 20 years time whatever u do and also in 20 years time your house will be be standing. It's cosmetic…

Also an expansion joint. It will probably be better to silicon it? What I don't like is that joints between panels are not properly rendered and look ugly.

1000000% definitely add insulation. I have in my home and it makes a big difference minimising sound transfer. Insulation is pretty cheap and definitely worth it
