Hi @chaustralia ,
Thank you for getting in touch. I would recommend checking out Pinwheel first of all, which provides payment processing for a variety of different “high risk” products. I would also recommend checking out Authorize.net which is available to merchants in Australia. Please be aware that each gateway will have their own terms and conditions when it comes to payment processing, so it’s always recommended to refer to their eligibility rules and speak to them directly if you have questions.
Kind regards,
