Another difference between Aussie practice and US practice is that here the use of a green (or green / yellow) wire for this application is actually forbidden.
The style of the connection has long been disallowed here - by local rules, if nothing else - since the 70's. At that time, there was a campaign against that method, asserting that such connections were too easily damaged by lawn mowers, weed whackers, and the like.
I think 'inductance' is the wrong word; I think the word we ar thinking of is 'impedence.' As in, a coil of wire has a greater impedence than a straight wire. Since impedence is an AC phenominum, I am not sure the coil would have any effect on current flow caused by a (DC) lightning strike.
