 #### Arrivals
-IFR aircraft inbound to YSBK will be cleared direct to the RNP IAF and [coordinated with SBA](#between-sba-and-tcu). They should be handed to SBA not below `A030`.
+IFR aircraft inbound to YSBK will generally follow the [recommended routing](../../controller-skills/routes/#recommended-routes) via the **Z97 airway** from the west, the **Z88 airway** from the north, or the **WHALE STAR** from the east. In all cases, **SBA** is responsible for issuing approach clearance to these aircraft.
 
 SBA will [coordinate with BK ADC](#bk-adc) and clear the aircraft for the approach.
 
 !!! note

+    By day VMC, IFR aircraft may be instructed to downgrade to VFR and processed via a [coded clearance](#bankstown-coded-clearances).
 
-Aircraft inbound from the south, west, and northwest should track via the **Z97 airway** and be processed via ESGID for the **RNP-Z** approach. This helps keep them clear of the YSWS SIDs/STARs and segregated (but not separated) from the YSSY STARs.
+Successive RNP approaches in IMC should only be authorised after the first aircraft lands at YSBK due to the conflict between the approach and published missed approach. In practice, this may translate to up to an 8 min sequence between arrivals.
 
-Aircraft inbound from the east should be processed via the STAR and be vectored in SWA airspace to facilitate descent. They should then be cleared via the **RNP-Y** approach.
+!!! tip
+    When traffic levels in the TMA are low, it may be possible to simplify the handling of aircraft inbound to YSBK through track shortening and/or providing descent inside CTA.

+
+=== "From the West"
+    Aircraft from the west do not meet the criteria for voiceless [coordination by Enroute](#arrivals-4) and will be heads-up coordinated. A requirement to reach **A060 by WELSH** should be passed to Enroute to relay to these aircraft. This will help segregate them from aircraft on the AKMIR STAR, however there is no separation assurance provided by the AKMIR STAR past **MUBDI** unless the YSBK arrival is descended further.
+
+    Particular care should be exercised between aircraft inbound to YSBK on the Z97 airway and aircraft departing YSSY on the **ANKUB SID**. The interaction works best when the YSBK arrival is descended below the YSSY departure, although it may be necessary to provide vectors to maintain lateral separation between the pair until vertical separation assurance exists.
+
+    The Z97 airway includes ESGID, which is the IAF for the RNP-Z approach. IFR aircraft should either be cleared for this approach or instructed to downgrade to VFR (if conditions are suitable) and processed via a coded clearance. In either case, **SBA** is responsible for issuing approach clearance or VFR tracking instructions.
+
+=== "From the North"
+    Aircraft from the north do not meet the criteria for voiceless [coordination by Enroute](#arrivals-4) and will be heads-up coordinated. A requirement to reach **A070 by YAKKA** should be passed to Enroute to relay to these aircraft. This will establish the aircraft OCTA and keep the MEPIL STAR clear for aircraft inbound to YSSY.
+
+    These aircraft shall be instructed to reach **A020 by OMUVU** and transferred to SBA prior to that position. **SBA** will issue airways clearance into the Class D airspace commencing at OMUVU.
+
+    The Z88 airway includes NIXOD, which is the IAF for the RNP-N approach (which terminates in the circling area and is not associated with a specific runway). IFR aircraft should either be cleared for this approach or instructed to downgrade to VFR (if conditions are suitable) and processed via a coded clearance. In either case, **SBA** is responsible for issuing approach clearance or VFR tracking instructions.
+
+=== "From the East via the STAR"
+    Aircraft via the STAR meet the criteria for voiceless coordination by Enroute and should be processed via the STAR, then provided with vectors or cleared direct to the IAF for the most appropriate approach. This may involve processing by **SWA**, however **SBA** is responsible for issuing approach clearance via the RNP-Y or RNP-Z. Alternatively, aircraft may be instructed to downgrade to VFR (if conditions are suitable) and processed via a VFR coded clearance.
 
-Aircraft inbound from the north should track via the **Z88 airway** and be processed via NIXOD for the **RNP-N** approach. This approach is only available to the circling area and may not be suitable during periods of low cloud or reduced visibility.
