What Noel said!
The wiring rules (AS/NZS 3000:2000) don't allow these fittings in the
same flush box unless the RG6 is insulated for 230V.

The interference would be minimal. The shock hazard would be small but
not small enough to satisfy electrical regulations.

Bottom line - you just can't legally do it, even if it wouldn't really
be a problem.
