Openstreetmap and Overpass API, How to get metadata of all children objects

Question

is it possible to return the metadata of members (or children)? Or return structured data for parent and child objects from OSM?

I have the following query which returns all wind farms in Australia, and lists the lat lon for the members (or children objects). However after numerous attempts I haven't worked out how to include the metadata (or tags) for the children, which in this case are "generator:method"="wind_turbine".

// @name AU wind farms

[out:json][timeout:25];
// fetch area “Australia” to search in
{{geocodeArea:Australia}}->.searchArea;
// gather results
(nwr(area.searchArea)["site"="wind_farm"];
nwr(area.searchArea)["plant:source"="wind"];);
// print results
out body geom;

So far I can only get the wind turbine data in a flat json format:

// @name AU wind turbines

[out:json][timeout:25];
// fetch area “Australia” to search in
{{geocodeArea:Australia}}->.searchArea;
// gather results
(nwr(area.searchArea)["generator:method"="wind_turbine"];);
// print results
out body geom;

Example wind farm: OSM Ararat Wind Farm

Example wind farm member / wind turbine: OSM Ararat Farm, Wind Turbine
