Adobe Commerce Cloud Sydney (AWS ap-southeast-2), best AU hosting choice?

For most Sydney Magento stores, yes, Adobe Commerce Cloud on AWS ap-southeast-2 (Sydney) is the right default. Why: sub-5ms TTFB to Sydney metro (CBD, Barangaroo, Surry Hills, North Sydney, Parramatta, Macquarie Park, Alexandria all on the same fibre ring), data stays onshore for Privacy Act + APPs data-residency expectations, Fastly CDN included (with the AU edge node), Adobe handles patching + scaling + PCI-DSS Level 1 audit. The AWS Sydney region (ap-southeast-2) is one of the oldest AWS regions outside the US, mature, three Availability Zones, full service coverage. Cost: A$1,800, A$5,000/month for typical M2 store at A$1M+ GMV. Alternatives we also support: AC3 Sydney (Aussie managed-hosting specialist, A$700, A$2,500/month, hands-on AEST support team in their North Sydney NOC, great for B2B clients who want a phone number to call when something breaks at 2 AM), Hyvä Cloud AU region (Hyvä-optimised stack, lighter-weight than Adobe Cloud, runs on AWS Sydney underneath), MyHost Sydney (budget AU host, A$200, A$800/month, good for <A$500k GMV stores), BigCloud Servers (AU SMB hosting), Cloudways Sydney (managed Magento on top of AWS ap-southeast-2), AWS ap-southeast-2 self-managed (EC2 + RDS Aurora + ElastiCache + OpenSearch, lowest cost but DevOps burden), GCP australia-southeast1 (Sydney), Azure Australia East (Sydney). We usually recommend Adobe Cloud Sydney for A$1M+ GMV stores and AC3 / Hyvä Cloud AU for smaller / B2B / control-sensitive stores. Avoid AWS Singapore for an AU-only audience, the 80ms latency hit costs you conversions.
