Need Australia-based Lawyer to Help Obtain UTR / SWIFT Reference for Freelancer.com Payments

I am an India-based freelancer receiving payments through Freelancer.com.

For GST compliance purposes, I need to obtain transaction-level banking evidence, specifically:

UTR (Unique Transaction Reference)
SWIFT Reference Number (if applicable)
Any supporting documentation confirming international origin of funds

The issue is that payments are routed via intermediary banking channels, and my local bank in India cannot provide these details.

What I Need:

I am looking for a lawyer or financial/legal consultant based in Australia who can:

Advise on how Freelancer.com processes international payments
Help identify whether SWIFT/UTR exists at source level
Assist in obtaining (or formally requesting):
SWIFT MT103 or equivalent
Transaction trail / remittance proof
Guide on legal documentation that can support cross-border nature of payments

Ideal Candidate:

Based in Australia
Experience with:
Cross-border payments
Fintech / payment gateways
International remittance systems
