Just understand that the following likely have to paid out of this settlement
1. Legal fees - I suspect the lawyers took the case on a "no win, no pay" basis. That means "Big win = big pay." Not ideal, but the only way some people can access the legal system
2. Repayment of all the expenses (medical and loss of earnings) that have so far been paid by WorkCover - on the basis that WorkCover have to be repaid if another party is held liable. The State Government is keen to ensure it doesn't pay if someone else will pay.
So the final amount to look after the claimant for the next 40+ years (or whatever the actuaries decided) will be far less than the amount quoted by the media.
