A SO cadet upgrading to JFO has no more T/O and Ldg experience than 4 years previously when they flew in Adelaide. Not sure what this T/O, Ldg experience is that you are asking about, if you can pass the upgrade you will be a JFO if you can't you won't be and will be fired.
There will be no progress on housing until the first international cadets have enough time as a JFO and all start leaving for other jobs, CX will then provide just enough to make it worthwhile staying.
