Thanks to TheOldMiner
These are the main areas http://tools.geofabrik.de/osmi/?view=areas&lon=148.11749&lat=-20.12145&zoom=9

I am likely to be 'the other user' but have been unable to fix any due to not being familiar with the area and limited ability to interpret the Bing imagery for the wetland areas so I have abandoned my efforts to fix. There is the following data that could likely assist but as far as I know we don't have specific permission to use on the OSM http://www.ehp.qld.gov.au/wetlandmaps/

Please ignore, I see you have corrected it.

Hi
You have used +31 (Netherlands) for the country code in the phone number.
Did you mean for this to be +61 (Australia) instead

Hi Domhenry
Just curious to know how you get the height info for the buildings.

Welcome to the Openstreetmap.org
You need to read more of the tutorial and add the correct tags for your edit to display.

Welcome to the Openstreetmap.org
You have added a few shop=bookmaker to the map where none exist.
Are you able to correct these edits in the 2 changesets you have uploaded?

My comment was for no one in particular, but thanks for tidying up.

I have added all the company tags to the correct address point. I did not add to building as it appears several companies occupy the same building.

Your spam and inappropriate tags on Plenty Road have been deleted.
If you want to add business details add all the tags to the building it occupies (not the road) and leave out the spam.

As far as I know the comment is not able to be changed after uploading. Adding a comment to the changeset with the correct remarks is fine. I have had to do that occasionally.

Hi Sukhdeep, the name tag is meant to be the name of your shop. The big place across the street normally lays claim to Murdoch Uni.
Perhaps you were wanting to enter your suburb name, etc.
Please see these tags that you can add.

Hi Tom
Welcome to the Openstreetmap.
House names are only entered if the house really has a name, like some old historic homesteads. You are welcome to add other details such as ...

I have deleted the personal details of your name from the house as it is a public map and personal details are not required.
If the house *is* actually named as you suggested by your edit, then feel free to add it back.

Hi Jack
welcome to Openstreetmap. We prefer that you don't enter personal details like your name on the houses you map, thanks.

Hi,
welcome to the Openstreetmap.
I re-tagged the residential area as landuse=residential. Street names are ok.

Hi Robert
welcome to the Openstreetmap.
The map is public and I deleted your name from the building. We don't enter personal details, but the house number and details like that are welcome.
Names on houses are only entered if the house really has a name.
addr=*

The Openstreetmap is a public map so please don't put your friends names on the houses.
Thanks
