Or, does United rebook them for you and if so, does that mean baggage allowances from the initial international ticket carry through?
One way or another, you're not going to be catching a connecting flight after flying LAX-SYD (presuming the rules don't change before your travel date). The mandatory quarantining occurs in your port of arrival, so that would be Sydney.
If you were to book it and then "miss" your connection, your ticket would be gone. It's unlikely either UA or QF would be interested in re-instating the ticket after the fact (and there's less than zero chance JQ would). If you were to contact them before departure it's likely UA would change the date for the connecting flight, although there's no guarantee that they would even be it wouldn't trigger a re-pricing (depending on on the fare rules).
The other option would be to look for routes via Asia that can drop you straight into MEL and quarantine there. Further flying overall, but no need to have two distinct trips.
A second ticket for the domestic leg would make far more sense - although realistically it's had to say with certainty because nobody really know what's the quarantine/quota rules are going to be like in January.
