Not the hugest bargain around, but might be handy for those who need it. I was looking for a 2 x F-connector wall plate, to move my antenna cable onto the wall plate that already has Optus cable. They were $6.95 @ Jaycar, and the one with the phone socket is $5.95.
For those who get/will be getting FTTN or FTTC NBN, you can connect the phone line up to the RJ12 port.
hmm, still a matter of getting all 3 feeds to the same spot, wall plate is the easy bit.
