How early before a flight can you get into the Qantas lounge at Melbourne?

Hi guys, I have a flight at 12.30 on Wednesday the 22nd from Melbourne to Sydney. I have to leave the house early, how long before your flight can you get into the lounge?

Correct me if I'm wrong, but, I don't think there's a time limit for entering the lounges on the day of your flight.

No limit. I have been there all day in the past.

Bags I am not sure - always have carry on domestically. Website will tell you I'm sure.

Kitch, are you talking about the domestic lounge or the international lounge? For domestic you can check in as early as you want. For international, if you have bags to check you could be limited to three hours before the flight, if it's just hand-luggage only then you can check in online and go to the lounge as early as you want. However only the first class lounge is worth visiting early.

I have checked my bags in 9 hours before my international flight & spent the time in the lounge
