Does the owner of a property (X) who offers to pay the full costs of a new fence between two properties obtain any benefits / privileges under the Fencing Act Victoria 1968? Specifically, I am worried X's offer to pay the whole cost of the fence is a tactic to quash any objections we may have about the development of his property. (ie. he is trying to use the offer as leverage).

Should I be concerned about X's offer ?
