"According to the Reserve Bank’s website, coins are legal tender for payment of amounts which are limited as follows: Not exceeding $5 if any combination of 5c, 10c, 20c and 50c coins are offered; and not exceeding 10 times the face value of the coin if $1 or $2 coins are offered"
Literally being treated the same as everyone else though :/
