I don't see it as any sort of formal integration so much as just that all of ACT's numbers match the NSW number that ends at the border. This isn't in and of itself anything special: in most cases in Australia where a route crosses any state line it has the same number on both sides (though it may switch between N/A/B/C). WA achieves 100% match with neighboring states as well.

Furthermore, the name of the system is "New South Wales B Roads"... someone looking for a B road in ACT isn't necessarily going to think to look there with that name.
Personally, I see two reasonable paths here. One is for ausb to be left as all one nationwide system the same as was done with ausm, ausa, and ausn. But if it's going to be split up by state, ACT needs to be split into its own system too for the sake of consistency.
AUS-QLD N42:- OK
AUS-QLD N46:- OK
AUS-QLD N79:- OK
AUS-QLD N83:- QLD84_W -> WilDevRd_N (since QLD 84 is not signed north of A6)
- QLD84_E -> WilDevRd_S (since QLD 84 is not signed north of A6)
- UruSouRd -> UraSouRd
AUS-TAS N1:- C316 needs a recenter
- C29 -> C529
- RosRd -> C305_S
- C305 -> C305_N
- C132/189 -> C132/C189 (per labeling guidelines)
- DiaRd -> DialRd
AUS-TAS N1Lau:- OK
AUS-WA N1:- 171.31 mile gap between EucTelRd and CocRawRd. Consider adding a couple visible points to shorten, e.g. at Mundrabilla.
- HarRd -> HarRd_S
- RavHeaHauRte_E -> RavHHRte_E or HeaHauRte_E
- HopRavRd -> ColSt
- RavHeaHauRte_W -> RavHHRte_W or HeaHauRte_W
- WA107 -> WA40
- BorBreBayRd -> BBBayRd or BorBreRd
- WA30 -> NorRd
- add point for WA30 junction at wye just north of the roundabout where the old point is (note that per signage WA 30 appears to end at N1, does not extend south of it into town)
- DenMtBarRd -> DenMBRd or MtBarRd
- ManBayRd -> ManBeaRd
- WheCoaRd -> T259_S
- add point for T259_N at Eastbourne Rd
- WigRd -> WilRd
- BroHwy -> T251_S
- GreBoyBroRd -> GreBBRd
- BlaRivDr -> T251_N
- GrimRd -> GriRd
- DonBoyBroRd -> DonBBRd
- BunOutRingRd -> BunORRd or OutRingRd or BunRingRd
- OldCoaRd_N -> T260 (and therefore OldCoaRd_S -> OldCoaRd)
- JohRd needs a recenter
- ForHwy -> WA2_S
- SawRd -> DawRd
- ManRd -> ManRd_W
- EnnAv -> ManRd_E
- SafBayRd -> WA18
- DixRd -> WA22
- PatRd -> PatRd_S
- KwiBeaRd -> T202
- CocRd -> WA12
- SpeAve -> WA14
- WA2 -> WA2/6
- BelSt -> WA55
- WA41 -> KalRd (WA41 ends at WA3 per signage, doesn't extend this far north)
- ChiRd -> T359
- point WA86 needs to be moved north to new junction
- CatRoa -> CatRd
- EneBooRd -> EneCooRd
- TriRd -> TriSt
- AjaKalRd -> T354
- 113.61 mile gap between that point and DenhamRd. Consider adding visible points to shorten.
- WA129 -> WA142
- RoePtSamRd -> PSRoeRd or PtSamRd
- 353.56 mile visible distance between WA138 and BrooHwy. Can definitely add some points in here.
- 136.88 mile visible distance between DerHwy and ForRd_Fit. Could use additional points to shorten gap.
- 106.08 mile visible distance between ForRd_Fit and YiyComRd. There are opportunities to add points.
- WA5 -> TanRd (this road becomes NT5 but does not have a number in WA)
- 193.79 mile visible distance between N96 and VicHwy. There are opportunities to add points.
