One further thing to consider for M&M are Senator companion awards. In case a flight award is on LH/OS/LX/LO only, you will need half the miles for your companion only. The only problem for you is that OS will stop its flights to Australia in March, so companion award will not be of much use to you in MEL.

If awards on LH/OS/LX/LO only are an option for you, the earn/burn ratio for M&M is very good when flying paid business class and redeeming business awards for two using SEN companion award. Say you regularly fly BRU-VIE-MEL-VIE-BRU in business class. Each return flight earns you 49,024 miles. The cost of an award on this route for two is only 240,000 miles. So, flying this route 5 times gives you an award on the route for 2 persons! This would mean an earn/burn ratio of 2.45.
