USPS has suspended most deliveries to Australia and New Zealand, the only ones going through are priority express packages, which are super expensive. I sell the occasional pedal to that part of the world and I've had to cancel a couple orders because priority express international is somewhere around $70 USD just for a single pedal in a small box. I haven't found any cheaper method (UPS, FedEx and DHL were absurdly expensive) but also haven't really looked at any forward companies.
One Australian customer requested that I build his pedal anyway and just hold onto it until shipping opens back up so it's sitting on a shelf now, but if there are any reasonable forwarding companies out there it would save the wait.
EDIT: just looked at packagehopper.myus.com looks like I can get a pedal from Chicago to Australia for about $30, only $5 more than I used to pay pre-COVID.
