Hi

It is always advisable to be upfront with any medical queries that you have, it may well up the premium should they class this as a pre existing medical condition which I very much doubt. With regards to the fruit picking etc if they clearly state you won't be covered then unfortunately this is the case and not worth the risk. I would check that the company you are going to work for indeed has it's own insurance and also just double check with Medicare what is covered.
