It seems there will be a new AUSTRALIAN PLATYPUS coin: https://www.legislation.gov.au/Details/F2020L01132
They have been many other 1/3oz platinum coins before and they usually all get shipped overseas to the dealer that commissions the project.
Thanks for pointing this out. I did not check the details of R113: $30 At least 99.95% platinum 10.423 ± 0.050 [grams]
