I understand it's used for plating other conductors due to it's resistance to corrosion, however, is there actually any practical application for Gold's conductivity?
For example, when used as a gold plating, does any current really pass through it
Please leave suggestions, i'm desperate for ideas :D

Brass is a really good conductor of electrical current.
Now pull a plug out of you home wall socket, something that has been running for ages, like the fridge (don't forget to put it back! Mum will kill you....)
Look at the tarnish, filth and mung on it. At 250 volts this matters a little.
For audio or video equipment, at 5 to 9 volts, that mung matters a great deal - the signals will be squelched, distorted or at least partially lost forever.
So gold, that does not hardly tarnish, is totally worth while for concert quality music or video systems, but we do not bother with the expense of it for higher voltage utility devices.

Yes, the three best conductors are: Silver > Gold > Copper. However, copper is used most often because it is cheap. Gold is only slightly more conducting than copper, and silver is only slightly better than gold, however, silver is cheaper, so it is very rare to see gold used as a conductor.

Gold is very good for conducting electricity. Gold is only beaten by Silver and Copper in conductivity. Since copper is much cheaper and is protected by the outside of the wire, only the plugs and ports need to be plated in gold.
-
YES gold is a great conductor, AND it oxidizes much slower than Silver or Copper, so it maintains it great conductivity much longer.

Gold is an extremely good conductor.

Yes gold is an amazing conductor.

Gold is an excellent conductor, but not so much better as to make it worth the added cost

It's one of the best
