This park does not exist any more. Duke Street in fact does extend through here now. To check for yourself, look at the more current Bing Aerial Imagery.

Please revert your edit.

this isn't a wooded area. Can you please explain your edit

take a look at this proposal - it looks pretty awesome

osm.wiki/Proposed_features/area:highway

Also can I start mapping roads with area:highway if that is technically correct?

I noticed my mistake after I read this "meme" on the openstreetmap subreddit on reddit https://i.redd.it/7r3xp43m4hxz.png

What should I do? manually re-align the wooded area /grass/residential area?

The previous alignment of the beach was not correct. It crossed itself and I assume someone that worked on it previously did not notice the beach was connected to it which resulted in a pointy (unnatural) section of beach.

Here's the local government area map - http://www.coffsharbour.nsw.gov.au/coffs-and-council/running-council/PublishingImages/Coffs_LGA_Localities-Map1.jpg

If you zoom in you can see coffs harbour and it goes north from the breakwater - not following the coastline.

@Warin61 I fixed the boundary. Sorry for the problem

I looked up the "OSM Example" for Harbors - osm.org/edit#map=16/53.3889/-6.0644 Howth port and it comes with the administrative boundary attached to the coastline.

Do you want me to change it back?
