Well as person that has once been involved in the insurance broking game ,I would only say, come May~July this is an uneasy period for accounts that are attacked on renewals.....you either sharpen the pencil,or start looking for alternative employment. There use to be a saying @ the Lloyd's brokerage house I use to work at , in the mid 1970's>1980's
"1% of F**ck all, is F**ck all! 1% of something is worth all !."
I think this applies very much in Oz.
So any brokerage that manages to keep its accounts in place will survive for another year. Start to loose big accounts ,well bang goes your pencil sharpener...............Nett Premium income!
