Thanks for the reply and your reasons seems fine.

Hi
roads and tracks on private property are able to be mapped. They should also have access tags added if known, such as access=private.
Please only delete roads on private property if the property is yours or the ways were mapped by you.
It is preferred not to delete other mappers work unless it no longer depicts what is on the ground.

I added office=company to this edit, assuming your business is located here.

This seems an obvious misunderstanding between the stated source and OSM practice and is reverted.

Hi
This seems not to meet the openstreetmap use of a tertiary link.
Though this road may link major roads, the osm use is for slip roads, not the the road itself between the major toads.
highway=tertiary%20link?uselang=en-GB

Hi
private roads do get mapped on private land.
You are expected to add access tags and/or gates to such roads if known instead of deleting another's mapping.
They may be also accessed by utility maintenance vehicles.

I deleted both tags

Hi
Why have you added the following tags to this building?
description=Really cool
name=not my house

Fixed by simplifying

Hi
Thanks for the quick reply.
I have added the tag back in now.
Cheers

Hi
You seem to have deleted the highway=motorway_link from way with ref 80 below

Hi
There is an edit error here that needs correcting http://tools.geofabrik.de/osmi/?view=areas&lon=152.96897&lat=-27.62454&zoom=18
Please ignore if you have already corrected it

I have reverted this changeset.

I reverted this edit as I expected this remains a secondary college.

Hi
I unnglued caravan site from roadway centrelines and creek and joined entrance roads to frontage road

Hi
I removed the address point and details off the main road centreline and placed it just east of the road and south of the creek. Please shift it to the correct building location and preferably map the roadway leading to it.
I also fixed the road by removing the bridge tag and placing bridges only over the small sections of the road that span the creek.

Hi
I deleted the Compassion Temple and Black Sheep Farm as you placed it on the roadway. Please place it off the roadway, preferably over the building and draw the roadway leading to the building.

Hi
Can you discuss with the Australian Osm community before importing such data.

The building tag is meant for depicting the building outline and not the block of land.

This appears incorrectly mapped and bears no relationship to bounds of natural areas viewed on satellite imagery.
