This is a very good question and you should ask your health fund this question. One health fund has not increased dental rebates across the board since 1994. Many funds do not increase dental rebates annually. Private health funds in Australia have made in excess of $7.2 billion surplus (profit) in general treatment cover in the last 10 years which has not been returned to contributors as increased rebates. It is now $3billion surplus in just the last 3 years.
