Kitchen upgrade. Electrical installation and isolation switches

I'm in South Australia in case it makes a difference to rules! Installing a new flat pack kitchen soon with Gas cook-top (bottled gas) and electric under bench oven. I have seen and been told, conflicting things regarding the legal requirements for an isolation switch. If I have a Gas cook-top, do I still have to have an isolation switch installed for the Electric oven??
Thanks in anticipation, Lesley N.

I have employed a builder to remove the two centre piers on my carport, which is under the main roof of the house.
I asked them to replace the concrete footings and 2 remaining brick piers, at the corners, with steel support posts. as I don't know the condition of the footings.They haven't done this and and have used the existing concrete footings with dyna bolts.The posts they have installed are only 3mm thick walls.The contract was verbally agreed and they are claiming that there was no mention of the above work and that it isn't needed.

Kitchen waste taps

I have a wheelchair user so we are installing a floating kitchen bench where the waste trap below the sink is exposed. For aesthetic reasons we want this to be as shallow as possible. Where can I find regulations or can you advise regulations on what is required for a kitchen sink waste trap. I have seen "Shallow Traps" but they have a shallower depth of water seal - are there limits regulated here?
Or am I allowed a bathroom sink style bottle trap?

Demolition in Victoria

do I need a demolition license/registration to knock down small structures like chook sheds, garages, patios, pet enclosures and such?

Anything small such as these? Is it once you get to single storey structures that you need to be licensed/registered

Thinking of starting small in demo and want to be sure I am allowed to knock down certain things.



very thin NON combustible material to line bottom of wooden shelf

I want the name of a product that is fire resistant or at least retardant to attach to the bottom of of my wooden shelf which extends over the back 2 back gas hobs. It must be very thin and effective.

My home was built in the 50"s so the shelf has been in the same place since built.

However lately I have been told that it is outside the regulations, does anyone know of a suitable product, as I will not change the shelf.

Thank you for any input that will aid me in this issue

Sliding doors

We have just built a new house. Our back entry is two big sliding doors which measure 3600 x 2400 in size each. It has three double glazing glass panels each side. It is very heavy to operate. However it has only one set of handle on only one side. We are struggling to operate them especially the three panels without any handle to grip or hold.

However the supplier claim that it is the market standard that it have only one handle on one side of the doors disregards how big the doors are.

Kitchen Bench - Height allowance of bench between a join

I would like to know the allowable Australian Standard to height variation on a kitchen benchtop between a join.

Our bench which is only 7mm in height and sits on a 33mm substrate is uneven between one of the two joins.

As you can see in the attached photo we've put a spirit level on the join to show how it's not flush.

The join is on a standard 600mm benchtop and the height variation starts approx 15mm from the benchtop edge and all the way to tiles.
