With the KEEWI 8 approach, no matter where you're coming from, you'll fly to either KONDA, CARBA .. etc ZANEY, and from there, to SUNNY (Unless ZANEY or LOCKA)... then you're off to KEEWI. And that's the transition. Any of those, to KEEWI.
Perhaps, or you may be cleared direct to KEEWI, depending on how ATC is feeling.
The chart describes the procedure to follow from there, for the ALPHA approach looking at the AIP chart you then track from KEEWI to BASIL, which is also the inital approach fix for the Localiser approach, and then conduct the localiser approach via the 24 mile arc from Cairns which takes you around to intercept the localiser. There's no ILS on runway 33, just the localiser, and the ALPHA is an entirely instrument procedure until you get to the end of the localiser approach. The STAR ALPHA procedure needs to be looked at alongside the localiser 33 instrument approach procedure which it feeds you into - you definitely dont just cut in! There's high terrain either side of the localiser course, it is depicted on the Localiser 33 approach charts, cutting in would take you into that terrain.
Theres also ITORT EYSAW APUSS ECATT heading west out of Townsville.
