At least for the next week, it's a two hour stay in MEL with QF10 timetabled to arrive at gate at 2045 and QF93 to depart at 2245.
While QF10 may sometimes arrive early, and there's usually padding of at least half an hour in international flights of any decent length, allowing only two hours for passengers to alight, the new cabin and flight deck crews to come on board, catering to be unloaded and loaded, the aircraft hastily cleaned (not very well!), freight and mail unloaded and loaded, refueling and finally departing passengers boarding is tight. MEL thankfully lacks a curfew but my guess is QF93 will frequently depart late.
