The QF and MH need to be in the same PNR for bags to go through.
QF don't through check bags on separate PNRs.
It seems like you have a MEL-SIN award flight. If you pay cash for the SIN-KUL flight on MH (instead of booking it as an award), QF ‘should’ be able to check to check it right through as there is an exception for transits which involve an award flight transiting to a revenue flight.
The should is in inverted commas as it is dependent on you getting a check in agent who is aware of the policy and is able to help. At a major QF hub like MEL, you should have a higher chance of success.

Thanks, I did read the part about Qantas doesn't check through bags on separate PNR, with separate airlines, even if its OW. Yes MEL-SIN is an award flight. So one way to get around it is to buy the ticket with cash, and they should honor the policy and check through baggage to KUL. Prefer to use points as I've racked up 2 million+ points over last few years, even if the short flight is 20,000 points + $76 taxes vs $475 cash.
I rang the call centre 10 minutes ago this morning, and was advised by the agent (not sure which call centre) that I couldn't make a change to the existing booking to add-on a second connecting flight from SIN-KUL, reason being the booking needs to be re-ticketed, and to do so, there needs to be current award availability for MEL-SIN to do so. Is this accurate? OR should I try to call again hoping for a more experienced agent?
(This agent initially even said I couldn't check through baggage even on same booking as all flights need to be Qantas, so I assume he's just not very experienced.)
Flight arrives in SIN at 5:45pm, there is MH616 at 7:15pm (1.5 hours transit), and MH610 at 9:20pm (3.5 hours). So if I had to collect bags and check-in again, I'd have to go for the latter flight. I do have Qantas Gold, QR Plat (from Virgin status match, expiring 31 March), so could probably access to Qantas First lounge in SIN? Is it probably just better to book the latter flight so I experience QF First lounge, since I've never been in there once (haven't utilised the QR Plat before lol). QF1 departs midnight so it should open yeah? Also, I would save the 5,000 x2 change booking fee for making a separate booking.
