OK, so I have a number of Arlec “Grid Connect” devices, and I have to admit I’ve never used them with the Grid Connect app. When I click on one of them in the Smart Life app, it shows up with the Arlec branding so maybe that’s what you mean. Basically, Grid Connect is Tuya with a different skin, so I suspect what you are seeing is normal.
Firstly: Maybe you are looking at the wrong data centre? For me (also Australia) all my devices are in Central Europe. Make sure you can see them in https://iot.tuya.com/ first.
Secondly: Not all devices are currently supported by the integration, and this might be the case with you even though it claims to support fans (Tuya - Home Assistant). This was also the case with the old integration, although it did seem to support a few more things. In my case, for example, I’ve lost access to some motion sensor flood lights. The good news though is that this new integration is officially supported by Tuya, and they do plan to bring more devices in over time.
