Ok, I mapped that as one building as only a low zoom image showing the building is available. The two buildings and the carpark that appear incomplete are on the corner of Ballarat and Butlers roads. It's fine to leave further mapping until more suitable imagery becomes available in the editor. Thanks for your help.

I have mapped the three new buildings using Ersi imagery but the two buildings in the bottom right of the carpark seem to be still partially completed as does the carpark here. You may be able to complete that area if you are local to the area

I apologise for my haste…later imagery shows a newly constructed building here.

Why have you mapped a physio in a car park?

Is this a hospital or a clinic?
amenity=hospital
amenity=clinic

Hi, I removed the ‘Cubby house’ name tag from the small building on the property.
The name tag is not used to describe things but is reserved for things that really do carry a name such as ‘Shirlow Avenue’.

Hi, welcome to osm.
I fixed the phone format on both your edits.

Hi, I reverted this change because you accidentally dragged a road node across a few streets.
Can you edit it again to make the changes you want.

no response, edited tags

no response, deleted

no response, changed to clinic, fixed opening hours

Finally rendered the four islands I added a coastline to but only on zoom 15 so far

Hi, I have reverted your edits as you have added the business to a suburban roadway that is obviously not at the address you have listed for the business.
You should add a node within the city building you listed and add the tags to that.
You may find it helpful to use a site like https://www.onosm.org/# to add the proper tags.

I added a coastline to Fairway Island to get it to render on the standard layer (and the Tracestrack Topo layer).
Another three island within the coastline were also affected and already had a natural tag. I the changed them to single member multipolygons and added natural=coastline to the way so that the ways did not need to be duplicated for the natural=coastline tag.
Feel free to revert/remove/alter if that doesn't suit.
Coastlines take longer to render...

Thanks Rowan, I’ll do that tomorrow if time permits

Is the building named "The Mill Markets" on OSM the same site.
If so, should I merge you info to the building and use the name you have provided instead?

Hi, you have placed this business on the footway. Can you place it over the part of the building it operates from thanks.

Is this a hospital or a clinic?
amenity=hospital
amenity=clinic

Not sure how soon the changes to rendering of multipolygons may take.

I added another water relation MP but it hasn't rendered the island as yet...
relation/18088652
Maybe having these two separate water mp around the island causes the problem...do there need to two separate areas?
