For any QLD/TAS/SA/WA applicants who are attempting to do both Unsw & Monash interviews on 24 Jan (I know one is trying to) I have retrieved the following info from my Monash email last year.
==================
Our (Monash) MMI session times are detailed below.
Session / Registration / Sequestered / Complete
Session 1 / 7:45 am / Yes - after MMI / 12:15 pm
Session 2 / 9:45 am / Yes - after MMI / 2:00 pm
Session 3 / 12:15 pm / Yes - after MMI / 4:30 pm
Session 4 / 12:15 pm / Yes - before MMI / 4:30 pm
Each MMI circuit will take about 90 minutes to complete. To maintain the interview content security, it may be necessary to sequester you as per the table above. Sessions that involve sequestering will be up to 4.5 hours in length.
==================
UNSW is 45 min panel plus admin so allow 1 hour, good thing is IIRC the last time slot was 6pm or 7pm. One possible way is do Monash session 1, show your Unsw interview time & air ticket to request leaving at 10am. That gives 8 hours travel time to arrive at Unsw by 6pm.
It can also be done by asking Monash for interview on 25 Jan, the above suggestion is because the person I know probably wants to do WSU on 25th as well. If he pulls this off I'll nominate him for a gold star for efforts
Btw if same as last year Monash session is by online booking, log in early to get the session you want. UNSW session is by replying to Admissions email indicating 4 prefs out of 10 time slots, someone at Admissions then manually arranges to give you the highest pref possible.
