If you did have to fly down south during the week, your best bet would be to track via Mittagong and Goulburn, then just south of Braidwood follow the Araluen Valley across to the coast at Moruya at 7,500ft or even 9,500ft depending on cloud clearance requirements. The extra height above 5,000ft is needed for glide to safe landing area in case your fuel to noise converter stops.
