Hi,
Your tagging some ways as boundaries.. but these ways are not closed so cannot be the entire boundary ... for example Way: 405794390. These boundaries you are trying to map should be entered as relationships ...

Way: 318676779 looks like animal quarters ... certainly not a hanger? Unless it is a guilder or two. But I'd think there would be vehicle tracks then.

Ok, I have place this node into a way that I made from bing, and placed appropriate tags on the way. I then copied this way 3 times to show what is evident in bing imagery. AFL is usually played on a pitch with an oval shape .. all these pitches are rectangular? Anyway .. makes the map look better.

Again sport=rugby for Way: 413291277?

Way: 238732436 .. this too is rugby?

Hi,
Way: 413293177 has sport=football ... football is not specific enough ... I thing this is rugby?

Hi,
Way: 270248268 sport=football changed to sport=rugby as per the got web site. football is not specific enough.

post office appears to be 1 km to the east now. node/1737974502

node/300463574 has no physical feature - will not render. Suggest its tags are moved to some appropriate physical feature.
