In January, with two friends, I did a two week intensive in Intermediate Classical Greek at the Macquarie Ancient Languages School. It was 3 hrs/day of classes following Lushnig's An Introduction to Ancient Greek: A Literary Approach, which I enjoyed immensely.
I received a letter today advertising a one-week intensive running 2-6 July, with Intermediate and Advanced levels for both Classical Greek and Koine Greek (plus an intro to Mycenaean!). The Advanced Koine course caught my eye, it runs in the afternoons and tackles sections from Hebrews. Cost is $110 if paid by 4 June. Info is here:

The winter school has Greek, Latin, Hebrew, Aramaic, Akkadian, Aramaic, plus hieroglyphics; the summer school covered a few more languages in addition to these.
