3000 Dollars - Elizabeth II 6th Portrait - Australian Kangaroo - Gold Bullion

Perth Mint introduced the one-kilogram denomination in this series as part of its ongoing effort to serve institutional bullion buyers who prefer a single large-format piece over multiples of smaller coins. The .9999 fineness — four nines — requires an additional refining step beyond the three-nines standard used by most sovereign mints, a specification Perth has maintained since launching its Gold Kangaroo program in 1989.

The reverse design rotates annually, a deliberate policy established to discourage melting by keeping the numismatic premium marginally above spot for recent dates.
