For your problem you should start a new topic of discussion under the osm Oceania community.

You can't abuse the OpenStreetMap in this way to test your navigation.
I have reverted your changeset.
It might be better to discuss the problem at the OSM Community forum https://community.openstreetmap.org/c/communities/oceania/73
There has been a recent discussion about a Tesla routing problem and this post may be of general interest.
There is help available here is you explain the problem you are encountering.

I already fixed the coastline earlier today

I deleted The Good Guys

I think it's fixed now, cheers.

I can help fixing this if you prefer.

I have reverted the changeset which will restore the admin boundary for Clifton Beach. The mp boundary ways are also shared by neighbouring admin boundaries and only carry a geometry source tag.

The members of the relation for Clifton Beach should not carry the tags you added. These tags are only added to the multipolygon relation.
If you intend to edit relations, I suggest you use the Josm editor instead so that you can at least get a better appreciation of the relation extent and how it is constructed.

There appears to be a couple of breaks in the coastline here…

@snorch I have reverted this changeset as I expect that an amenity of this nature is unlikely on a road verge near a footway

Can you tell me more about the animal breeding facility you have mapped here

koof67 appears to have deleted all the wooded areas again in changeset/147205318

Your changeset comment says '2 & 2A 2 Kidston Parade' but you have only added the building tag.
You should also add the address details using addr:housenumber and addr:street and also if applicable addr:unit
The suburb and state are already mapped as areas separately so no need to add those to house addressses

Correction…changeset comment should read ‘very coarse’

You need to place Bob's Prestige Lawnmowing business over the building he operates from instead of over the lawn he mows.
It it is his home then add office=company also to the point you place there.

No response. Deleted as unable to resolve remotely.

Corrected name, postcode, added suburb, phone

Changed to company=transport

Hi, you have added amenity=post_office to the Neil Mansel Transport point.
I would have expected company=logistics or company=transport instead.
company=logistics
company=transport
