I will only add support if they are also rebranded febit devices, but I imagine that the (single) switches could even be added as a generic device. Dual switches and dimmers are a horse of a different colour though. I would be happy to help out, but as I dont own any of the devices I cant actually do it by myself.
Please make sure you do your diligence and ensure that these devices are certified for use in Australia, when I looked at them (on whirlpool) it was ambiguous as to whether or not they are certified (some were, some were not, some were expired). If a device which is not certified causes a fire it will void your home insurance.
Personally myself and other Australians tend to use either fibaro/aeotec behind the Clipsal Saturn range, but it does tend to get pricey.
