Nothing, aside from any heat buildup from the small losses of the the socket being combined in the close proximity of the one outlet. Those small losses quickly multiply into lots of watts (heat) at high voltage and current. Exasperating this, those losses increase with the temperature rise https://en.m.wikipedia.org/wiki/Thermal_runaway#Electrical_engineering

Yes, but as has just been pointed out, what is the difference between daisy-chaining between single sockets, and using the internal strapping between dual sockets.

The fact remains that (my) dual sockets are labelled 10A each, and NO dual sockets are labelled 10A total.

Using that logic none are labelled with a total rating higher than 10A either. The 3112 standard requires each socket to be labelled but you can't add socket ratings. This does seem to be a gap in the system but the only answer at the moment seems to be that if you are concerned about the load "use singles or fittings with a separate input per socket rather than internal connections." Any change to the Standard would need to be agreed by both Australia and New Zealand. That probably means it would take forever.

Probably covered by ensuring that you don’t drop more than 5% of the supply voltage as per the Standards for domestic over your total cable run eg 20A 230V over 30Meters of 2.5mm tps is 4.7% iirc

Protect the circuit for 16A and you’re covered.

Found last night electrician had wired up the relay wrong for a light circuit carrying 6A of 12v. Relay is connected to switch via CAT6A and rather than just the current for the relay coil, was carrying the entire current of the load through it! Actually it didn't even get that warm... It was a new installation and hadn't left the area with the lights on for a long time so perhaps it would over a while.

So looks like OP has his answer?, what if I run a clothes washing machine and tumble dryer off a socket at the same time? It's been working so far for me but now worry I actually shouldn't be doing it.

Probably shouldn't, but I've done that plenty with no issues so far. Washing machine likely drawers less load than a heater.

Depends on the washing machine. Front loaders usually head their own water, so that element draws about 1800W from memory.

I wouldn't.
