Questions about building inspection condition

Hi all

Asking about putting building inspection clause in a contract. I would like to find out has anybody successfully got vendor to remediate an issue that is NOT exactly considered a “major defect” before?

I understand that if a major defect is found, the buyer has the option to pull out of the contract. (or alternatively the vendor can offer to fix the defect as long as the buyer agrees). But how likely is the vendor to fix a minor defect?

Also, when you putting down a building inspection clause, do you get the choice to customize the wording or can you only go with the “standard wording”?

For example, when making offers for properties in New Zealand, I always put down “This agreement is conditional upon the purchasing being 100% satisfied with the content of a building inspection report” <— notice how it says 100% satisfied, not just “major defect”.

So I am wondering if it is possible to customize wording like that in Australia?
