If you find that you need help with this, let me know.

"probably needs cleaning up but I'm unsure how to do that "
You do need to fix this and a good start would be to use an editor like Josm that has better capacity to edit and validate such relations.

Select the ‘analyze on map’ tab to see where the gaps are

I reverted this

The inners I added to the multipolygon should be tagged islets too I guess, instead of just wetland areas. I’ll do that in the next few days.

Can you recheck the relation you have edited. It makes little sense to me.

I added four wetland areas covered with vegetation as inners to the water multipolygon extending from Rockhampton barrage to the sea and Josm validator finds it ok.

Looks like some fixing up to be done still

no response, business shifted to previous position.

I have reverted this changeset.

Hi, you appear to have drawn a primary highway over top of a trunk highway.
A duplication like this is seen as unexpected by me. What are you trying to achieve?

Hi, please map waterways in the direction the water flows - this is always downhill. I have corrected this changeset.

Hi, Squires Loft is placed in the water - can you relocate it over the building it operates from.

Best to use Josm for such large features

Hi, the roundabout is already mapped tagged way/548130634
If you were wanting to map the boundary of the inside ring of concrete you could tag barrier=kerb/curb?
barrier=kerb
Or if there was a garden on it you could map leisure=garden
Can you delete way you added or change the tagging thanks.

Hi, please draw waterways in the direction of flow, always downhill to eventually flow in to streams and river to meet the sea.
