Our research focused on the identification and characterisation of galaxies in the ZoA, using the new near-infrared (NIR) data from the VVVX survey in the regions that cover the southern Galactic disc (230{deg}<l<350{deg}). We used our previously-established procedure based on photometric and morphological criteria to identify galaxies. The large data volume collected by the VVVX required alternatives to visual inspection, including artificial intelligence techniques, such as classifiers based on neural networks. The VVV NIR galaxy catalogue (VVV NIRGC III) is presented, covering the southern Galactic disc, significantly extending the vision down to Ks0=16mag throughout the ZoA. This catalogue provides positions, photometric and morphological parameters for a total of 167559 galaxies with their probabilities determined by the CNN and XGBoost algorithms based on image and photometric data, respectively. The construction of the catalogue involves the employment of optimal probability criteria. 14% of these galaxies were confirmed by visual inspection or by matching with previous catalogues. The peculiarities exhibited by distinct regions across the Galactic disc, along with the characteristics of the galaxies, are thoroughly examined. The catalogue serves as a valuable resource for extragalactic studies within the ZoA, providing a crucial complement to the forthcoming radio catalogues and future surveys utilizing the Vera C. Rubin Observatory and the Nancy Grace Roman Space Telescope. We present a deep galaxy map, covering a 1080 sq. deg. region (230{deg}<l<350{deg} and |b|<4.5{deg}), which reveals that the apparent galaxy density is predominantly influenced by foreground extinction from the Milky Way. However, the presence of intrinsic inhomogeneities, potentially associated with candidate galaxy groups or clusters and filaments, is also discernible.2025A&A...700A..33Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/700/A33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/502/601 : The VVV near-IR galaxy catalogue (Baravalle+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/700/A33https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/700/A33http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/700/A33https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/700/A33https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/700/A33http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/700/A33GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/700/A33/nirgc3 (VVV NIRGC III)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/700/A33/nirgc3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/700/A33/nirgc3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/700/A33/nirgc3?GETtext/xml+votable180.050000true106.6154167-16.66708330.0055555555555555563/613 615 4/1301 1344 2333 2335 2357 2359 2365-2367 2370-2371 2376 2378 2400 2402 2484-2485 2487 2493 2495 2536 2538 5/5213 5380 5382 5384-5385 9303 9309-9311 9337 9339 9425 9427 9433 9435 9457-9459 9472 9474 9478-9479 9488 9490 9508 9510 9516 9632 9634 9640 9642 9944-9945 9947 9969 9971 9984 9986 9992 9994 10016 10018 10024 10026 10112 10114 10120 10122-10123 10158 10363 10366-10367 10394-10397 10405-10407 10409-10410 10416 10423 10426-10429 10434-10437 10447-10448 10458-10461 10465-10466 10468 10535-10537 10540 10546-10547 10549-10550 10558-10559 10574-10575 10586-10587 10590 10592-10593 10602-10606 10616-10617 10626-10627 10629-10630 10640-10641 10752 10758-10759 10763-10764 10768 10784 6/20805 20849 20851 20857 20860-20861 21526 21532 21534 21552-21553 21556-21557 37205-37207 37209 37211 37231 37233-37235 37317 37319 37325-37327 37699 37705 37707 37729 37731 37737 37739 37825 37827 37892 37901-37903 37906-37907 37909-37911 37956-37958 37964 37984-37986 38036-38038 38044 38072-38074 38416 38418 38424 38532 38534 38540 38542 38564 38566 39221 39223 39229 39231 39317 39319 39325 39327 39349 39351 39357 39359 39785 39787 39873 39875 39908-39909 39911 39917 39919 40452 40454 40460 40462 40484 40486 40600 40602 40624 40626-40627 41406-41407 41449-41451 41458-41459 41462-41463 41535 41563 41565-41567 41573-41575 41592-41594 41596 41615 41619 41635 41644-41646 41648-41650 41663 41668 41672 41690-41691 41701-41703 41720-41722 41731 41734-41735 41752-41754 41756-41757 41760-41762 41764 41786-41787 41796-41797 41808 41822-41823 41826-41827 41829-41831 41848-41849 41857-41859 41868-41870 41876-41878 41880 41888 41920 42127 42138-42139 42152-42153 42156 42164-42166 42182-42183 42193-42195 42204-42205 42208-42209 42219 42222-42223 42231 42283 42286-42287 42338-42339 42342-42343 42354-42355 42384-42386 42388-42389 42402-42403 42405-42407 42428-42430 42472-42473 42476-42477 42479 42503 42514-42515 42524-42526 42528-42530 42532-42533 42568-42569 42576-42578 42580-42581 43012 43016 43023 43027 43029-43031 43045-43047 43049-43051 43060 43064 43076-43077 43080 43140 43144-43146https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/700/A33?format=asciiInfrareddefaultJ/A+A/700/A33/nirgc3VVV NIRGC IIIrecnoRecord number assigned by the VizieR team.
