There was a case in NSW that was finally resolved in 2010 regarding "aerotoxicity" that occured in 1992.
Whether it exists or not, you're looking at a long hard slog to first get it recognised as your health complaint and then second to actually get some form of compensation. Unless you're critically ill after a fume event, I wouldn't be looking for a diagnosis, you'd just be pouring money down the drain at the moment.
