Recently I got job in Australia. Little are the chances for me coming back. I have more than dozen licenses and weapons which I want to store them safe for at least 10 years away from moisture rust and other things.

Need help from experts as how to preserve these firearms as far as I Google it

Needs a tough plastic bag preferably of a good size
And a vacuum device to sucks all air out and at the end seal that plastic bag

Please guide me

Do I need to thoroughly lubricate the weapons before packing if yes than lubricate it with what ? Oil or grease .
How to take care of stock
Where to get these tough quality plastic bags and

Where I can get that vacuum creating and sealing machine ?

Any other feedback or words of advise are very much required as time is short before I leave. Want to get this burden off my head
