Contract question regarding building and pest report [VIC]

I recently made an offer on a property subject to finance and building and pest report. When I received the contract to sign I noticed the boxes relating to building report and pest report had not been ticked. I asked for this to be amended and when I received the new version of the contract I noticed the boxes had not been ticked but the wording "Subject to building and pest inspection within 10 days of signing of this contract. If anything major comes up in the report buyer may end this contract" had been added.

This is my first property purchase so wanted to make sure this essential means the same thing as ticking the two boxes. My assumption is it was written in to make it 10 days rather than the 14 days mentioned under General Conditions 21 & 22?

I would have referred this question to my conveyancer however they are now on leave for the next week. Any advice would be much appreciated.

 

why are you signing without legal advice?
It sounds like that clause wasn't drawn up by a solicitor as it is a bit vague - a lot vague really. What does 'major' mean? 'comes up'?
