A lobelia but which one?
I took the photo with a grey paper as background and one entire plant without grey - the flower colour was deep blue not pinkish as some photos suggest.

According to Plantnet, gibbosa leaves have smooth margins, and rarely a few narrow teeth ( as in your photo). Dentata has broadly lobed leaves. The professionals rely on microscopic examination of the seeds for IDing the tall annual Lobelias, which is useless in the field.

What about L. browniana? i'm confused because the lobelia key of plantnet does not list this species however it is an accepted taxon see https://vicflora.rbg.vic.gov.au/flora/taxon/714c569c-1479-443c-8bf2-04932dfc1093 and listed in the ACT Census. There is one record on Black Mountain by R. Purdie; see http://canberra.naturemapr.org/Community/Sightings/Details/3368263.

I had not heard about browniana. It is in Vicflora, but there is no key to differentiate it from gibbosa. The description states that the leaves are withered when the flowers open, which does not fit your photo. It used to be a subspecies of gibbosa, so is very like it. https://vicflora.rbg.vic.gov.au/flora/taxon/714c569c-1479-443c-8bf2-04932dfc1093

It seems to me that L browniana is a split from L gibbosa; see for instance http://saseedbank.com.au/species_information.php?rid=4985
The species occurs in eastern Australia; see this distribution map:
http://avh.ala.org.au/occurrences/search?taxa=Lobelia%20browniana#tab_mapView
and records for ACT:

Splits and mergers of taxa and resulting name changes are very confusing for me :-(
