Samsung Ring launching Down Under in mid-October
The first country in the South-East Asia and Oceania region to get the wearable.

I was disappointed when the Galaxy Ring wasn't announced for Australia back at Unpacked in July, but it turns out the wait wasn't too long.
Samsung has confirmed that the Galaxy Ring wearable will hit Australia in mid-October.
Right now there hasn't been any information on pricing, so expect that a bit closer to the actual release date. It's not going to be cheap though. It sells for US$$399.99, which is currently about AUD $600 in a direct exchange, so expect it to be higher than that.
