Just remember the MAPt is for the LOC approach only (NPA). The ILS is a precision approach which uses the DA as the point by which visual reference must be established, not an MDA. The MAPt for an ILS is the point where the DA intersects the electronic GP. Therefore, if you conduct the the Missed approach prior to the DA on an ILS, you can't physically track to this point, you just fly what the chart says. In the case of Cairns, you turn left without delay to track 015, and intercept the 15 DME arc, climbing to 3700'. Thinking about it logically, there is some high terrain immediately to the south of the airport, so if you are discontinuing the approach you really want to turn left and get the f#ck out of there ASAP!
