The official G-Shock site for Australia has a new domain name and URL at https://g-shockaustralia.com.au. It is also now offering e-commerce orders with free shipping, free returns up to 14 days, and a 2-year warranty on all watches. Payment methods include credit cards (Visa, MC, Amex), Paypal, Google Pay, and Shop Pay. Installment payments are also available with Afterpay. Shipping is limited to Australia only.
For non-Australians, the website offers the unique ability to browse by watch size. There are four sizes based on width. The listings in each section seem to be appropriate for the most part, with a few exceptions. (The GBX-100, despite its dimensions, is arguably more of a medium size. The GAS-100 and GD-120 series should be in the large section. Also, the GST-B200 appears to wear like more of a large size, though it has been listed as mid-size in a Casio catalog.)
