Duty-free Alcohol on Multiple Domestic Connections?

[Awesom Andy]

I'm planning to get a bottle from SIN duty free, but that would mean I'll have to take it onto my fully domestic status run. I'm not sure what the exact rules are these days for liquids on domestic flights, but would I get my bottle confiscated?

When buying the bottle in SIN, you get the duty free store to deliver it to your boarding gate (ie. clear security at the gate and then collect your purchased duty free before heading onto the plane). The duty free allowance for Australia is 2.25L of any alcoholic liquid, so you can buy up to that limit (essentially 3x750mL bottles) without needing to declare anything on arrival or pay any duty or tax in Australia.

At present there are no liquid restrictions on domestic flights, with the exception of domestic flights that depart from international terminals (a couple of examples being QF8 BNE-SYD and JQ35 SYD-MEL). Basically:

If your flight is on Virgin, you're fine.
If your flight is on Qantas, you're fine if the flight number is QF400 or above (QF1-QF399 depart from international terminals).
If you're on Jetstar, you're most likely fine, but just double-check the terminals.

Of course, if you're in any doubt at all, feel free to post any/all of your flight numbers and I'll be happy to double-check the terminals for you.

PS: Obviously, if you were looking to take the alcohol home with you on your final leg to SIN, you aren't able to (unless it's in your checked baggage), as the standard 100mL restrictions apply on international flights ex-AU... in that case, simply buy the alcohol duty-free on arrival at Changi subject to the Singapore duty free limits.

Thanks! That's one detailed post.
All the flights after my arrival in MEL will be from domestic terminals and the bottle will eventually be dropped off in SYD, so it looks like I'll be fine.
