Hey guys, thank you for your responses!
Change of Plans,
The only reason I considered MH over QF was because the MH flight departs at 6.45am, but the QF flight departs at 11.30pm that night!! The cost of the two flights were the same. I ended up choosing QF based on my status and luggage allowances just to be safe, but the downside is a 20 hour layover in SIN.
