Postcode not in records

A week ago I built an integration with this API and was testing with my home address in Brisbane with the validate and serviced-by endpoints with no problems. But today I was doing some testing as we are planning to deploy this integration on Monday and when I tested my home address with the validate endpoint I received some response information. But when checking the serviced-by endpoint with the data: endpoint: https://api.myfastway.com.au/api/addresses/serviced-by

{
    "fromRF": "BRI",
    "locality": "QLD",
    "postalCode": "4066",
    "lat": -27.4758781,
    "lng": 152.9978561
}

My auth token was obtained from: https://identity.fastway.org/connect/token I received a response with an error saying that "we don't appear to have that postcode in our records"

{
    "errors": [
        {
            "code": "PSC_PC_NF",
            "path": null,
            "message": "Sorry, we don't appear to have that postcode in our records (QLD 4066)",
            "suggestedValues": null,
            "logLevel": 0
        }
    ],
    "type": 2
}

I know for a fact this location should not fail like this. Any information on what I could be doing wrong or if there has been a change in the API that I am not aware of? I also tried with some new API keys as I read in another issue something that might work but still had the same error message.

Edit: I also tried to obtain an auth token from this end point https://identity.aramexconnect.com.au/connect/token with the scope code set as ac-api-au. I received a token and then tested the same serviced-by request and had the same issues. I even tested requesting with this url https://api.aramexconnect.com.au/api/addresses/serviced-by with my new auth token.
