Tagging a Showground

Is there a standard for tagging Show Grounds in Australia?

I found someone had proposed a tag but its appearing abandoned/inactive.

Wasn’t sure if I should use Park or Recreation Ground or something else.

Almost every regional town in Australia has its own show ground which is also a common place for tourists to set up a camping site while the showground is not being used for an event.

A ‘showground’ can be tagged landuse=recreation_ground with recreation_ground=showground.

Some showgrounds have camping, sports activities too … they can all be tagged together.
