Help Looking for remote controled powerboard with only one socket.

I do some work for disabled people, often children. I am looking for a Remote Controlled Power board with only 1 socket and importantly one button for both on and off. Rules preclude modifying the 240 volt part but the remote control needs to be modified to enable use of a lrge external switch (Jellybean Switch) for use by a disabled person. The Click Powerboard from Bunnings provides the function but is overkill and the oother 3 sokets have to be ignored.

Preferred source is Australia as it must be 240 volt Aus Socket design.
