Australian Transcription vs Otter.ai, Sonix & AWS Transcribe
What Australian businesses actually need from a transcription service — and how the options stack up.
The Australian context matters
Most transcription services are built for a global market. That's fine for many use cases. But Australian businesses operating under the Privacy Act 1988 (Cth) have a specific problem: APP 8 — the cross-border disclosure principle.
APP 8 requires that before you disclose personal information to an overseas recipient, you take reasonable steps to ensure that recipient won't breach the Australian Privacy Principles. In practice, this means sending audio recordings overseas to US-hosted services carries real legal exposure — not just theoretical risk.
Australian Transcription processes all audio on AWS infrastructure in Sydney. Your data never leaves Australia, so APP 8 obligations are never triggered. It's the only transcription API built around this constraint from the ground up.
With that framing in mind, here's how the main options compare.

Otter.ai
Otter.ai is primarily a meeting assistant, not a transcription API. It's good at real-time capture for Zoom and Google Meet, but it's subscription-based, stores recordings on US servers, and doesn't offer straightforward pay-per-minute API access. For Australian businesses needing programmatic transcription with data sovereignty, it's not the right fit.
Sonix
Sonix has strong editing tools and a clean web interface, making it popular for journalists and content creators. It does offer an API and pay-per-minute pricing, but at roughly $0.23/min (AUD) it's considerably more expensive than the alternatives. Data is stored on US servers, so APP 8 obligations apply when processing audio involving Australian individuals.
AWS Transcribe
AWS Transcribe is the closest competitor on data residency — you can configure it to use the ap-southeast-2 (Sydney) region. It also supports Australian English spelling. But "configurable" means it won't be Australian by default: you need to explicitly set the region, and you'll need an AWS account, IAM setup, and SDK integration. It's a reasonable choice for teams already deep in AWS. For everyone else, the overhead is significant compared to a purpose-built API with Australian residency by default.
On pricing, AWS Transcribe comes in around $0.042/min (AUD), which is more expensive than Australian Transcription's flat $0.02/min — and speaker diarization is charged separately on top.
