using keybase HortFlora key, this is Fraxinus excelsior, European Ash, see description at https://hortflora.rbg.vic.gov.au/taxon/ada20b8c-5340-11e7-b82b-005056b0018f
Buds are black, clearly seen in 3rd photo.

Yes buds are definitely blackish not brownish. So I tend to agree; it is not the very similar Desert Ash, F. angustifolia subsp angustifolia.

In MIS25 "Should not be planted near nature reserves"
See https://www.cityservices.act.gov.au/__data/assets/pdf_file/0009/1502874/Fraxinus-excelsior-Aurea.pdf
However there are very few records in ALA in Canberra area, so maybe it is not invasive like the desert ash, although it is said in Wikipedia to be naturalised in New Zealand.
Since it is easily identified from other ashes by the black buds, it would be good to have it listed separately in CNM and not lumped in with other species as Fraxinus sp. Then we have a chance to look at its invasiveness here.
We need to identify non-invasive exotic deciduous trees which are safe to use in urban plantings as well as the invasive ones.
Could it be added to the sleeper weeds still being sold priority list?

This species is evidently less common than F.angustifolia so maintaining Fraxinus species on the sleeper weeds list in it's place is fine I suspect. Unless Michael feels differently, my understanding is that this particular list is for species with known invasive potential that are still commonly planted - not the case here so probably not an appropriate listing. I'll check with one of my exotic plant contacts at the Sydney herbarium and add the species If he is satisfied that the ID is correct.

The tree has been planted in the nature reserve which is inappropriate independent of which Fraxinus species.
