There is just one snag on this great, I would say greatest idea of all times, which is this: since Australian miners do not control the supply they would be undercut by others, including by Russia.

"Russia is also a leading producer and exporter of minerals and gold. 90% of Russian exports to the United States are minerals or other raw materials.[citation needed] Russia is the largest diamond-producing nation in the world, estimated to produce over 33 million carats in 2013, or 25% of global output valued at over $3.4 billion, with state-owned ALROSA accounting for approximately 95% of all Russian production "

Therefore, if you want to make a fool of yourselves, which I must confess seems to be the norm, go ahead with your submissions to the micro-parties in the senate.
